Super Excited to be Presenting at International Conferences this Summer

Conferences are outstanding venues at which to exchange latest research results and ideas, to do networking, and to reconnect with colleagues from around the globe. And, when the conferences are located in beautiful locations, the experiences become even more special and worthwhile.

This summer will be a very busy one. I will soon be presenting 4 talks at 3 different conferences in 2 different countries.

My first talk is the opening keynote talk at the Game Theory Sing21 Conference in Naples, Italy. I am very grateful to Professor Annamaria Barbagallo for the invitation. The title of my keynote is: "Game Theory, Supply Chains, Labor, and Tariffs: Insights from Variational Inequalities."

The program for the conference is now available online: https://sites.google.com/view/sing-21/programme_1/scientific-programme

I will then travel to Linz, Austria to speak at the EUROPT Conference: https://www.jku.at/en/institute-of-business-analytics-and-technology-transformation/conference-europt-2026/ At that conference, I will present a paper that was co-authored with my Isenberg School PhD student, Samira Samadi, which was recently published in the Journal of the Operational Research Society (JORS). The paper, entitled, "Ad Valorem Tariffs in Global Supply Chain Networks and Impacts on Labor," can be accessed from the journal website: https://www.tandfonline.com/doi/full/10.1080/01605682.2025.2592758

The IFORS Conferences, which take place only every three years are some of my favorites! IFORS is the umbrella organization for national Operations Research Societies, including INFORMS. And, since the 2026 conference will take place in Vienna, it is one not to be missed. I love Austria and had a Fulbright at SOWI in Innsbruck, Austria. My family and I very much enjoyed living in Austria.

It will be an easy journey from Linz to Vienna.

Working on the two presentations for IFORS was very enjoyable. I would like to take the opportunity to thank Professor Gerhard-Wilhelm Weber for inviting me to speak in the stream: Moments in the History (and Future) of OR. Preparing my presentation, "Highlighting Some Historical Women in OR," took me on a very nostalgic journey since I was blessed to have known some of the truly remarkable female OR pioneers. And my other presentation at this conference is on a paper co-authored with two females: Samira Samadi and Professor Deniz Besik (who was my former PhD student at the Isenberg School): "Fresh Produce Spatial Price Equilibrium on General Networks: Capturing Commodity Quality Deterioration Through Endogenous Transportation Time Delay Functions with Capacities," which was recently published in the European Journal of Operational Research:  https://www.sciencedirect.com/science/article/abs/pii/S0377221726003759. Of course, in the former presentation, I will highlight the new initiative of  IFORS: GLOW - Global Leadership of Women in Operational Research!

Safe travels, everyone!

Looking Forward to Giving a Distinguished Engineering Lecture at Purdue University

I have been enjoying working on the presentation that I will be giving at Purdue University, after our mutual spring breaks next week.

I was actually scheduled to deliver a Distinguished Lecture in Engineering at Purdue in February, 2025 but my flights were cancelled because of snowstorms so we rescheduled for 2026 and in late March.

A few years back I was offered a faculty position at Purdue but I received a counteroffer from UMass Amherst, so I stayed at the Isenberg School of Management. It will be nice to be back at Purdue and to see its growth and changes.

My talk will cover a lot of territory on research I have done with wonderful colleagues and PhD students on agricultural supply chain networks, with a focus on policies and international trade as well as disruptions (and there have been and continue to be many) plus resilience.

And, after my presentation, there will be a panel, which will allow for additional discussions.

Travel and the exchange of ideas are truly wonderful aspects of being an academic. I am very grateful to all institutions and the faculty, students, and staff who are engaged in organizing seminar series!

Looking Forward to the 2025 INFORMS Conference in Atlanta!

All five presentations are now done! The 2025 INFORMS  conference will definitely be a whirlwind conference. It will take place October 26 -29, 2025. I am so looking forward to the talks, the social events, serendipitous encounters, the exhibits, and the various business meetings and special luncheons.

Detailed information on the conference is available here:https://meetings.informs.org/wordpress/annual/

Three of my PhD students will be coming - Ismael Pour, Samira Samadi, and Dana Hassani. 

Ismael will present our latest paper on integrated crop and cargo war risk insurance, co-authored with Borys Kormych of the Odesa Law Academy, which was recently published in the January 2026 issue of the International Transaction in Operational Research, and is available free access: 

https://onlinelibrary.wiley.com/doi/10.1111/itor.70038?af=R. 

I will speak on the panel in honor of Hani Mahmassani, who passed away on July 15, 2025. The panel is chaired by Karen Smilowitz, the Editor of Transportation Science and fellow panelists are: Srinivas Peeta, Michael Hyland, and Marco Nie. The panel will be a moving tribute to a leading scholar, educator, mentor, and friend, who is deeply missed.

Samira will present two of our papers (because my schedule is loaded with many meetings and conference events) - a paper, co-authored with Deniz Besik of the University of Richmond on a continuing passion of ours - impact on fresh produce quality of various supply chain disruptions - and the  paper, "Multicommodity Trade, Tariffs, and Rerouting," that is forthcoming in a very special edited volume: Convex and Variational Analysis with Applications: In Honor of Terry Rockafellar’s 90th Birthday, with Themistocles M. Rassias and Panos M. Pardalos as Editors, Springer Nature Switzerland AG; see: https://link.springer.com/book/9783032078599

Dana will present a paper of ours that was also recently published: "Quantification of International Trade Network Performance Under Disruptions to Supply, Transportation, and Demand Capacity, and Exchange Rates in Disasters." This paper was co-authored with colleagues at the Kyiv School of Economics (KSE): Oleg Nivievskyi and Pavlo Martyshev and appears in: Dynamics of Disasters- From Natural Phenomena to Human Activity, Ilias S. Kotsireas, Anna Nagurney, Panos M. Pardalos, Stephan Pickl, Chrysafis Vogiatzis, Editors, Springer Nature Switzerland AG; see:https://link.springer.com/book/10.1007/978-3-031-74006-0#toc

And on the first evening of the conference, I will receive the INFORMS President's Award, for which I am deeply grateful and very honored:  https://www.informs.org/News-Room/INFORMS-Releases/Awards-Releases/Anna-Nagurney-Honored-with-2025-INFORMS-President-s-Award

Excellent INFORMS Tune-Up Event Hosted by the UMass Amherst INFORMS Student Chapter!

Yesterday, the UMass Amherst INFORMS Student Chapter held its annual INFORMS Tune-Up event at which PhD students, who are chapter members, practice the presentations that they will give at the upcoming INFORMS Annual Meeting. This year, the conference will take place in Atlanta, Georgia, October 26-29, 2025. The website for the conference is here: https://www.informs.org/Meetings-Conferences/INFORMS-Conference-Calendar/2025-INFORMS-Annual-Meeting

The presenters and their titles are on the poster below.

It was great to have speakers from the Mechanical and Industrial Engineering Department (MIE) at UMass Amherst as well as from the Operations and Information Management (OIM) Department.

I very much enjoyed all the talks. Ali Jafari and Yukti Kathuria are from MIE and Samira Samadi, Ismael Pour, and Dana Hassani are from the OM side of OIM. The latter three are also my PhD students.

The audience included faculty and students and valuable comments and suggestions were given on the presentations and there were also great questions. It was an excellent practice session.

The presentations by Ali and Yukti focused on on unsupervised learning approaches and Bayesian networks to healthcare, respectively, and those by Samira, Ismael, and Dana were on food quality under trade disruptions, integrated crop and cargo war risk insurance, and the quantification of international trade network performance, respectively.

Samira's presentation was based on  a paper that we co-authored with Professor Deniz Besik of the University of Richmond.

Ismael's paper was based on a paper that we co-authored with Professor Borys Kormych of the Odesa Law Academy and which is the lead article in the January (2026) issue of the International Transactions in Operational Research. It is available for free here: 

https://onlinelibrary.wiley.com/doi/10.1111/itor.70038?af=R

Dana's paper, in turn, was also co-authored with me, and with colleagues at the Kyiv School of Economics (KSE), Oleg Nivievskyi and Pavlo Martyshev. The paper was published in the latest Dynamics of Disasters  (2024) co-edited volume: https://link.springer.com/chapter/10.1007/978-3-031-74006-0_7

Special thanks to faculty: Professor Peter Haas of the Manning College of Information and Computer Sciences, UMass Amherst, Professor Hari Balasubramanian of MIE,  and Professor Zihao Qu of OIM for taking the time to support the students and offering their suggestions. 

I took the nice photo below:

The pizza, fresh fruit, and coffee were delicious.

This student chapter will be recognized at the INFORMS Atlanta conference with the Cum Laude Award on October 27. We will have a nice group there to receive the award and to also celebrate!

I have been the chapter's Faculty Advisor since its inception in 2004 and have very much enjoyed seeing how the students have grown professionally and socially. I stay in touch with many once they receive their PhDs and go on to careers either in academia or industry!

The 2nd Virtual Conference on Ukraine was OUTSTANDING!

I'd like to thank KTH The Royal Institute of Technology in Stockholm, Sweden, for hosting our 2nd Virtual Conference on Ukraine August 22 and 23, 2025. It was truly outstanding. It was an intellectual feast with 3 Nobel Laureates in Economic Sciences: Daron Acemoglu, Roger Myerson, and Paul Krugman delivering keynotes along with Yuriy Gorodnichenko and Subal Kumbhakar. 

I was honored to also give a keynote (the first one) and have posted my presentation as well as that of my Isenberg School of Management, UMass Amherst PhD student Ismael M. Pour on the Supernetwork Center website: https://lnkd.in/gncCNfTK.

I would like to thank the President of KTH Royal Institute of Technology Anders Söderholm for his warm welcoming remarks as well as fellow members of the Organizing Committee: Lars Harvigson, Almas Heshmati, Hans Lööf, Paul Nystedt, Roman Sheremeta and Hans Westlund. I am grateful to all the presenters of papers as well as to the panelists who joined me in discussing: Challenges of Ukraine's Post-War Reconstruction. Thanks also to those who joined us from many different countries and engaged with us. The networks that we are building in support of Ukraine in terms of research, higher education, and policy-making are inspiring.

So many fascinating research questions are  percolating from this conference. The full program can be downloaded here: https://www.kth.se/ukraine-conference.

Thanks to UMass Amherst for issuing this nice press release: https://www.umass.edu/news/article/anna-nagurney-co-organizes-virtual-conference-featuring-three-nobel-laureates-map

Tomorrow we mark Ukraine's Independence Day in commemoration of the Declaration of Independence of 1991. Slava Ukraini.

My 3 PhD Students Will Present Our Recently Published Papers at the POMS Conference in Atlanta

The link to the video recording on Youtube is here: https://youtu.be/AIbWpVPM4uU

The above video recording also includes the presentation by Dr. Emma Freninger, which followed my presentation.

It was also very thoughtful of the CORS President to provide the above certificate. 

Thanks to my PhD students and all others who attended our virtual presentations with special thanks to Ismael Pour for writing up some of the highlights on the UMass Amherst INFORMS Student Chapter blog: https://websites.umass.edu/umassinf/2025/04/13/two-talks-in-one-day/

Our research on agricultural supply chain networks continues!

I Had a Great Time Speaking on Agricultural Supply Chain Networks at the University of Louisville in Kentucky

I returned from Louisville, Kentucky, past midnight. Immediately after my Humanitarian Logistics & Healthcare class at the Isenberg School of Management this past Thursday, I headed to Bradley airport for my flight to Detroit, and onwards to Louisville. I was very excited to have been invited to speak at the Department of Industrial Engineering at the University of Louisville. I was invited by Professor Lihui Bai, who, along with Professor Monica Gentili, co-directs the Logistics and Distribution Institute there. Professor Bai's PhD advisor at the University of Florida was Don Hearn, who was a good friend of my PhD advisor, Stella Dafermos of Brown University. Both have passed away.

It was also wonderful to be in a warmer climate with even flowers, after a very long winter in New England. It was great to meet in the morning with Professors Yunmei Liu and Thomas Riedel (a University of Massachusetts Amherst PhD alumnus), and to hear Professor Bai's PhD students speak on their fascinating research! One of Dr. Bai's PhD students is now working with one of my former PhD students and Dr. Bai.  A feature of academia that I love is all the connections that we have across the miles. Thanks also to Professor Brian Yueshuai He for meeting with me and discussing congestion pricing in Manhattan. He has a PhD from the Tandon School at NYU.   I thoroughly enjoyed speaking about agricultural supply chain networks and the many challenges that exist today (including tariffs) and how we quantify resilience and robustness under disaster scenarios. I also spoke on making an impact and interacting with journalists and the media as well as legislators. The Q&A was excellent after my presentation and we took a nice group photo.

The lunch at the University Club with Interim School of Business Dean Jeff Guan, the Chair of Computer Science and Engineering Wei Zhang, and Dr. Bai, which included oysters, was delicious. Another highlight was a group discussion with the IE PhD students, from so many countries (Turkey, Iran, Sri Lanka, Bangladesh....). Their energy, enthusiasm, and passion for their research are uplifting. I was surprised by a beautiful gift of stunning coasters presented to me with Kentucky Derby artwork on them.  We will use them when we toast the derby in early May! 

Sincerest thanks to all and especially to Professor Lihui Bai for the exceptional hospitality extended to me and for the great attention to detail in organizing my visit.

Many thanks to Delta for terrific 4 flights and for upgrades! 

Some Recent Coverage of Our Research in the Media

Next Monday, President-elect Donald Trump will be inaugurated for his second term in office. We can expect a quite dynamic, volatile period. I believe that the research that we have been doing will be extremely relevant from the modeling of tariffs and other policy instruments, such as quotas, and their impacts on a variety of product supply chains, to start.

I am gearing up for media inquiries and believe that, as an educator, it is very important to respond and to inform the public.

In the past few weeks, during the winter break at the University of Massachusetts, I have not only been getting ready for the spring semester and have also been writing papers, but, in addition, I've had several interviews and press releases on our work.

I am very pleased that the professional society of INFORMS issued a press release on our recent paper, "A Multiperiod, Multicommodity, Capacitated International Agricultural Trade Network Equilibrium Model with Applications to Ukraine in Wartime,"  published in Transportation Science. This paper I co-authored with my PhD student Dana Hassani and with Kyiv School of Economics (KSE) colleagues: Oleg Nivievskyi, and Pavlo Martyshev. The press release is available here: https://www.informs.org/News-Room/INFORMS-Releases/News-Releases/New-Study-Shows-How-Ukraine-War-Impacts-Global-Food-Supply-Chain-Urges-Alternative-Routes-for-Grains. Many thanks to Ashley Smith of INFORMS for this excellent writeup!

Also, UMass Amherst released this press announcement https://www.umass.edu/news/article/anna-nagurney-co-edits-new-book-disaster-management-research on my latest book, Dynamics of Disasters: From Natural Phenomena to Human Activity, co-edited with colleagues: Ilias S. Kotsireas, Panos M. Pardalos, Sten Pickl, and Chrys Vogiatzis and published by Springer Nature in late December. This book is extremely timely and contains 10 refereed chapters plus a preface. 

Recently, I was on Talk The Talk on WHMP to speak with Bill Newman and Bud Eisenberg on Trump, Tariffs and Tradeoffs: https://soundcloud.com/whmp/umass-isenberg-school-prof?in=whmp/sets/on-ice

We had such a lively discussion that they have asked me to come back after the inauguration.

And, just a few days ago, I had the pleasure of speaking with Janet Nguyen of Marketplace for her article, "Do blood donation centers sell your blood?" https://www.marketplace.org/2025/01/10/do-blood-donation-centers-sell-your-blood/ My research group has written many studies on blood supply chains and my article in The Conversation,  published shortly after the World Health Organization (WHO) declared the COVID-19 pandemic, helped to influence national policy on blood donations; see: https://annanagurney.blogspot.com/2023/12/honored-to-have-played-part-in.html

In late December I was interviewed for this deeply researched article on sanctions on Russia and chemicals published by Reuters: https://www.reuters.com/world/europe/russian-billionaires-whose-chemical-factories-fuel-russias-war-machine-2024-12-30/

And, not long before that, I was interviewed for this article in The New York Times on how Trump's tariffs would deal a big blow to the auto industry: https://www.nytimes.com/2024/11/26/business/trump-tariffs-mexico-canada-cars.html

Stay tuned! Interesting times await us!

I Enjoyed Speaking at the Robert H. Smith School of Business at the University of Maryland

This past Friday, I had the pleasure of delivering a talk in the Department of Decision, Operations & Information Technologies (DO&IT) Research Seminar Series at the Smith School of Business at the University of Maryland in College Park. I flew out after teaching on Thursday, October 31, 2024, which was Halloween, and returned late on Friday, November 1, 2024.

The title of my presentation was: "Agricultural Supply Chain Networks: Labor, Trade, Policies, and Resilience." The hospitality extended to me was wonderful. I very much enjoyed breakfast with PhD student Jiannan Xu and a delicious lunch with Chaired Professor Zhi-Long Chen, along with a great conversations. Meetings with Professors Raghu Raghavan, Xiaojia Guo, Alex Estes, and Ashish Kabra were delightful (and much too short). It was terrific to also hear some stories from Professor Bruce Golden as well as Professor Michael Fu, both of whom I had seen at the INFORMS Fellows Luncheon the previous week at the INFORMS Annual Meeting in Seattle! I enjoyed also chatting with Professor Wedad Elmaghraby. 

I had been to the University of Maryland several times since I had been on the Organizing Committee of the International Conference on Social Computing, Behavioral-Cultural Modeling, & Prediction a couple of years. However, this was my first trip to the Smith School of Business. There are a remarkable number of parallelisms between programs there and at the Isenberg School of Management, so the conversations were both informative and very interesting!

The Supply Chain Resilience (SCRIPS) Workshop in DC and More!

Last week I had the great pleasure of attending the SCRIPS (Supply Chain Resilience Issues, Problems and Solutions for the Homeland Security Enterprise) Workshop in Washington DC. The workshop was extraordinary, bringing together experts from government, academia and industry. The venue was excellent - the Texas A&M Bush Center, very close to The White House. 

It was an honor to be invited to deliver the keynote: Supply Chain Resilience Research: Insights from Agricultural & Food Supply Chains.

There were 3 themes to this workshop: the agricultural and food industry, the semiconductor industry, and ports. The organizers were incredibly prescient with the workshop taking place October 1 and 2, 2024, and the  East Coast and Gulf Coast dock workers set to go on strike at midnight on October 1!

I had anticipated a possible dock workers strike and wrote this article for  The Conversation: "Brown bananas, crowded ports, empty shelves: What to expect with the US dockworkers strike." The article was updated, once the strike was announced, before my keynote on October 1. I was busy going back and forth with my Editor.  The strike ended, preventing an economic disaster, within 3 days, and I had this article published in The Conversation: "Dockworkers pause strike after Biden administration’s appeal to patriotism hits the mark." 

I'd like to take the opportunity to thank the Department of Homeland Security (DHS) Supply Chain Resilience Center, the Center for Accelerating Operational Efficiency (CAOE) at Arizona State University and the Cross-Border Threat Screening and Supply Chain Defense Center (CBTS) at Texas A&M University, both DHS Centers of Excellence, for hosting this workshop. Special thanks to Ronald Askin for inviting me to speak with gratitude also to: Ross Maciejewski, Hilary Shackelford, and Pompelli Greg, who did an amazing job leading our food/ag industry break sessions. Appreciation is extended to: Cynthia Gerber, Manish Bansal and Sara Saberi for taking and sharing some of the nice photos in the collage below. Thanks to ALL for their participation and the incredibly inspiring insights and discussions.

It was terrific to see colleagues that I know from Operations Research from multiple universities at the workshop as well as to have CDC, FEMA, and, of course, DHS representatives taking part in the workshop.

It rained periodically during the workshop but, propitiously, the rain would stop when Robert, who is responsible for the amazing Ukraine Rally DC, would be out. I had brought my Ukrainian flag and, both last Monday and Tuesday, I joined him and others.

It was very special to meet refugees from Ukraine and even Kiran and Alan, who had worked in the Peace Corps in Ukraine, and I spoke Ukrainian with them!

My time in DC was incredibly rewarding and very special! And, while walking on the street back to my hotel one evening, a gentleman cried out my name and starting hugging me. He had just arrived from Mexico, was very familiar with my research, and was starting his new job at The World Bank the next day. He also knows our UMass Amherst Chancellor Javier Reyes, who is from Mexico. What a small world it is!

Kudos to the Organizers of the First International Virtual Conference on Ukraine

Today we mark Ukraine's Independence Day (33 years of independence) and the past two days I had the distinct pleasure of taking part in the first International Virtual Conference on Ukraine. It was excellent and I wanted to express my thanks to Professors Almas Heshmati, Lars Hartvigson, and Olena Nizalova for putting together such a timely and interesting program. It was laudable how the scheduling was done with speakers and participants from Hawaii, California, Texas, Massachusetts, multiple European countries, including Ukraine, as well as Vietnam, Australia, and Morroco!

Jonkoping International Business School (JIBS) in Sweden was the host of this virtual conference, in collaboration with its partners.

I took a snapshot of the closing session, which is posted below.

Each day, the conference began at 3AM, my time; but, despite this, I thoroughly enjoyed the sessions that I managed to join and, of course, it was an honor to present our latest research with my PhD student Dana Hassani and Kyiv School of Economics colleagues Oleg Nivievski and Pavlo Martyshev.

The presentation was based on our paper, noted above, which will be published any day now in the INFORMS journal Transportation Science. The slide deck of our presentation can be downloaded here. I was delighted that all the co-authors of our paper were present! Plus, I enjoyed "seeing" colleagues in Ukraine, with whom I have also published: Elena Besedina of the Kyiv School of Economics and Myroslava Kushnir of the Ukrainian Catholic University in Lviv.

I also thoroughly enjoyed being on a panel with: 

Pham Khanh NAM, UEH University Ho Chi Minh City, Vietnam

Hans LÖÖF, Royal Institute of Technology (KTH), Sweden

Vesa KANNIAINEN, University of Helsinki, Finland

Mykola TKACHENKO, CEO of SOE Prozorro (Transparency), Ukraine.

Yuriy BILAN, regrettably, could not make our panel, as scheduled.

A remarkable amount of information was exchanged and the discussions were terrific.

The keynote talks by Roman Sheremeta and Yuriy Gorodnichenko were excellent! I wish that all presentations could have been recorded and posted since with the different time zones it was challenging to hear all in real time.

Themes that resonated throughout included: the resilience of Ukrainians; the fact that Russia's war on Ukraine is a massive threat to global security; Ukraine needs immense support from its allies; economic & military aid to Ukraine is the best investment; agriculture and IT continue to be shining lights in Ukraine whereas steel production has essentially collapsed; investing in transportation routes is critical and keeping maritime routes safe and efficient; human capital must be brought back and nurtured; security is of the utmost importance; damages are immense to educational institutions, healthcare, critical infrastructure (energy, transportation, logistics, supply chains), and the environment, and so much more!

I was impressed how much researchers and practitioners and even PhD students who took part want to help. There was emphasis on the need to get research results in front of policy and decision-makers more quickly.

Information on this conference can be found here. 

The full program has been posted here.

Thanks to All Those Who Organize Conferences

This is going to be a very busy but exciting summer with many conferences to present at.

It takes a lot of time and effort to organize a successful conference from the venue selection to the invitation of keynote and other speakers, the organization of exciting sessions, and, of course, the various social and networking events and even panels. 

Conferences allow for the formal exchange of the latest research and also for many encounters, often occurring with serendipity. Friendships can even be made and wonderful memories established. It is great that, after a multiyear hiatus due to COVID-19, conferences are now taking place in person and with great enthusiasm!

Conferences can be huge or smaller and more focused and all play important roles.

In the next month alone, I will be giving talks at conferences in Greece (at the conference in honor of Pardalos with many friends in attendance), Denmark (at the Euro Conference, at which I will see quite a few of my former PhD students, who are now successful professors), and Italy (at the VINEPA Conference).

Thankful to be an invited speaker at the VINEPA (Variational Inequalities, Nash Equilibrium Problems and Applications) Conference in Catania, Italy. This conference will focus on some of my favorite methodological tools. 

Many thanks to the organizers of this conference. I have published journal articles with all the organizers, except for one!

Talks that I will present at the first 3 conferences have now been prepared. Deniz Besik of the University of Richmond will deliver a paper on our latest work at the Euro Conference in Copenhagen and is finalizing that presentation. I am thankful to my excellent collaborators, including colleagues at the Kyiv School of Economics (KSE) in Ukraine as well as my Isenberg School of Management PhD students.

Additional information on conferences, can be found on the Supernetwork Center website.

My Isenberg School of Management PhD Student Dana Hassani Receives the Outstanding Doctoral Student Research Award

As the 2023-2024 academic year was growing to a close, there were many celebratory events including my department's award ceremony that  I had blogged about.

And, at the final All School Meeting of the Isenberg School on May 9, 2024, there were faculty and PhD students recognized for research and teaching as well as staff for their accomplishments.

I was thrilled to hear that my Isenberg School PhD student, Dana Hassani, who has completed almost two and a half years in our doctoral program in Operations Management, was the sole recipient of the 2024 Isenberg School Outstanding Doctoral Research Award! I had nominated Dana for this award.

Below is a collage of photos taken after the announcement and prior to the Senior Barbecue that followed.

Dana has already had two journal articles published, one in the European Journal of Operational Research, and the other one in the Journal of Global Optimization.

Both of these papers, Dana co-authored with me and with colleagues at the Kyiv School of Economics (KSE) in Ukraine, Professor Oleg Nivievskyi and Dr. Pavlo Martyshev. Preprints of these and other papers of ours can be found on the Supernetwork Center website: https://supernet.isenberg.umass.edu/dart.html These papers are reflective of a wonderful collaboration began through the UMass Amherst - KSE partnership, which was established after the full-scale invasion of Ukraine by Russia on February 24, 2022. Pavlo was one of 15 Virtual Scholars in our first round and was placed with me as a Faculty Host.

In addition, we, recently, heard that another joint paper of ours, "Quantification of International Trade Network Performance Under Disruptions to Supply, Transportation, and Demand Capacity, and Exchange Rates in Disasters," has been accepted for publication in: Dynamics of Disasters- From Natural Phenomena to Human Activity, I.S. Kotsireas, A. Nagurney, P.M. Pardalos, S. Pickl, C. Vogiatzis, Editors, Springer Nature Switzerland AG.

The achievement of Dana's receipt of this award is quite impressive since there are 7 departments in the Isenberg School of Management.

The research on international agricultural trade network equilibrium problems continues, with various policy interventions, analysis of disruptions due to the war, as well as impacts on food security. 

Our KSE colleagues inspire us as do all Ukrainians fighting for their freedom and that of democracies globally.

Congratulations and Kudos - Virtual Center for Supernetworks in 2023

As the Founding Director of the Virtual Center for Supernetworks, which was established at the Isenberg School in 2001 (shortly before 9/11), I find it important, as another year draws to a close, to reflect upon the achievements of the Center and its Associates during these challenging times.

2023 was a remarkable year, in which we celebrated 15 Virtual Scholars in Ukraine, part of the UMass Amherst - Kyiv School of Economics (KSE) partnership. In the spring 2023, we had the honor and pleasure of helping to host the visit of the President of KSE, Dr. Tymofiy Mylovanov in February and the visit of the Rector of KSE, Dr. Tymofii Brik, in May, at which we also took part in a symposium featuring faculty hosts at UMass Amherst and the Virtual Scholars in Ukraine. Many thanks to the International Programs Office at UMass Amherst, including Vice Provost for Global Affairs Dr. Kalpen Trivedi, and to the Isenberg School and the Provost's Office for the outstanding support of this very important program that helps to reduce brain drain from Ukraine.

For the EJOR paper, "Multicommodity International Agricultural Trade Network Equilibrium: Competition for Limited Production and Transportation Capacity Under Disaster Scenarios with Implications for Food Security," Dana received the inaugural prize from my OIM department, for this A level publication with a monetary award of $750. In May, 2023, Center Associates Professors Deniz Besik and Pritha Dutta and I published the paper, "An Integrated Multitiered Supply Chain Network Model of Competing Agricultural Firms and Processing Firms: The Case of Fresh Produce and Quality," in EJOR.

And, with Professor Elena Besedina of KSE, we published a paper in Operations Research Forum. Much of our research with colleagues in Ukraine focuses on agricultural supply chains and impacts of Russia's war on them with the importance of alternative routes for exports quantified as well as the use of various policies for international trade enhancement.

We welcomed a new Center Associate, Dr. Gabriela Colajanni, with whom, and with Center Associates Professor Patrizia Daniele and Professor Ladimer S. Nagurney, we have been actively publishing on UAVs (drones).

Our research papers can be found on the Supernetwork Center website.

In addition, as part of the partnership, UMass Amherst welcomed 4 female undergraduate students from KSE! We hosted a special panel with them through the auspices of the UMass Amherst INFORMS Student Chapter and there is now even a video of an additional interview posted on the chapter's youtube channel. It has been an extraordinary experience interacting with these remarkable ambassadors for Ukraine as they enjoy their experiences at UMass Amherst very much. Our great Isenberg School Dean Anne P. Massey even hosted a lunch in their honor.

And, this past summer, I had the honor of co-organizing another Dynamics of Disasters (DOD) conference, which took place in Piraeus, Greece, and attracted conferees from many different countries. We are now in the process of editing the Proceedings volume. 

Speaking of books, I was thrilled that my Labor and Supply Chain Networks was published by Springer in 2023. It's wonderful to see al the libraries that now carry it.

Shortly after the DOD conference, and with a lovely meeting with Center Associate Professor Patrizia Daniele and her family in Madrid, I headed to the IFORS conference in Santiago, at which I delivered a keynote talk. It was wonderful to see colleagues from around the globe at this conference.

INFORMS in Phoenix served as a reunion for several of us, and it was wonderful to see Center Associates Professors Deniz Besik, Dmytro Matsypura, and Shivani Shukla there with Professor Zugang Liu also taking part. At this conference the UMass Amherst INFORMS Student Chapter was recognized with the Magna Cum Laude Award. I have had the honor of serving as the chapter's Faculty Advisor since 2004, whehn the chapter was established.

And big congratulations are in order to Center Associates Shivani Shukla and Dong "Michelle" Li, both of whom were recognized with promotion and tenure this year at their respective institutions of the University of San Francisco and Babson College.

Congratulations also to Center Associate Sara Saberi of  WPI, who was appointed the Norton Assistant Professor in 2023.

We continue to be very engaged with the media - some of our writings can be found here and interviews here.

Thank you for the support. Let's work together to make 2024 a better year than 2023 with all the pain and suffering now on our planet.

News Coverage on Our Latest Research

Real world events inform the research of my group at the Supernetwork Center at the Isenberg School of Management, that I founded in 2001 and continue to direct. 

Since the onset of the COVID-19 pandemic, we have continued to model and solve a spectrum of supply chain network problems that have been affected by various disruptions, which now, sadly, for almost 2 years, have also included major disruptions to agricultural trade caused by Russia's full-scale war on Ukraine. Our research, documented in journal articles and book chapters, has continued to quantify the impacts of labor shortages and security issues and blockages associated with transportation, production capacity limitations, along with the repercussions of Russia pulling out of the Black Sea Grain Initiative. We have also investigated the impacts of numerous trade policies from tariffs to quotas and have been heavily focusing on agricultural and food supply chains and associated food insecurity.

Our research on agricultural supply chains and international trade has been enriched by our collaborations with scholars in Ukraine, through the unique, outstanding partnership between UMass Amherst and the Kyiv School of Economics (KSE) that I have blogged about.

It is very much appreciated when the research that we are involved in gets attention from the news media. 

UMass Amherst issued this release on the paper, "Ukraine – Addressing the domestic humanitarian crisis and the effects of the war on global food systems,"  that I was deeply honored to contribute to and which was presented by my KSE colleague, Professor Oleg Nivievskyi, at the Vatican in May at the Workshop on Food and Humanitarian Crises. The paper can be directly accessed here.

Also, the University World News published a very moving article by Nathan M. Greenfield: "Partnership with US scholars helps to keep Ukraine HE alive." 

In the article,  Greenfield notes our paper, "Multicommodity international agricultural trade network equilibrium: Competition for limited production and transportation capacity under disaster scenarios with implications for food security, "  just published in the European Journal of Operational Research and done with my Isenberg School PhD student Dana Hassani and KSE scholars: Professor Oleg Nivievskyi and Dr. Pavlo Martyshev. 

In addition, the article in University World News discusses the recent paper I wrote with KSE Professor Elena Besedina, "A multicommodity spatial price equilibrium model with exchange rates and non-tariff measures for agri-food international trade," which was published in Operations Research Forum.

Preprints of the above papers, as well as others of our research group can be found on the Supernetworks Center site.

Collaborations across continents during wartime help to reduce brain drain and also deepen the research insights. Very grateful for the collaborations with scholars in Ukraine, which continue. Giving enhanced visibility to scholars in Ukraine provides valuable professional and psychological support during very challenging times.

Many thanks  for the news coverage!

The Amazing IFORS Conference in Santiago, Chile

I hope that everyone who took part in the amazing IFORS Conference in Santiago, Chile, which took place July 10-14, 2023, has safely and comfortably returned to their home destinations.

The conference, which is a triennial one, was face to face and attracted over 700 presentations and 900 registrants from around the globe.

Kudos to the Co-Chairs of the Local Organizing Committee: Professors Rafael Epstein and Jorge Vera, and to the Chair of the Scientific Program - Professor Alice Smith and to their teams for putting together such an informative and rich scientific as well as social program. And even the weather cooperated - the winter while we were in Santiago was quite mild.

It has been an incredibly busy several weeks, since, shortly before the IFORS Conference, I had co-organized the Dynamics of Disasters Conference in Greece. 

It was so inspiring to see the great attendance and enthusiasm of the conferees and, I must add that, on my direct flight from Madrid to Santiago on Iberia, there were several conferees from Italy (Paolo Toth, Grazia Speranza, and Claudia Archetti) and, just after passport control, I had the pleasure of seeing the INFORMS President Laura Albert. It was wonderful to stroll to the conference venues and to be greeted and to share greetings with conferees. It was truly special to have exchanges with both Professors Tom Magnanti and Fred Hillier, luminaries in Operations Research.

The below collage was prepared as a memento of the conference.

I was thrilled to see my latest book, "Labor and Supply Chain Networks," on display at the Springer book at the exhibition hall at the conference and very much enjoyed speaking to the Springer Editors: Matt Amboy, Razia Amzad, and Jialin Yan. 

I also very much enjoyed the plenary and keynote sessions as well other sessions plus Editorial Board meetings of both the International Transactions in Operational Research (ITOR) and the European Journal of Operational Research (EJOR).

Many thanks to Celso C. Ribeiro, the Editor of ITOR, and to Roman Slowinski, the Editor of EJOR, for such informative meetings!

With the size of the conference and the two venues, I regret that I did not have a chance to speak with as many conferees as I would have liked to. Additional highlights included meeting colleagues that one had interacted with virtually in the pandemic and finally got to meet in person, including the amazing Anand Subramanian, the developer and interviewer behind the outstanding youtube series Subjectto_

And Professor Subrmanian, with some assistance, brought 16 of his special mugs, to present those who were at the conference and had had the pleasure and honor of being interviewed by him! I will treasure my mug. He has, to-date conducted 72 interviews - an extraordinary effort of historical scientific value.

I'd like to thank Professor Margaret Brandeau for her warm introduction to my keynote talk and I am grateful to all those who came to my presentation. I am grateful to my UMass Amherst engineering colleague Professor Chaitra Gopalappa for taking the photo below.

It was wonderful to also see my UMass Amherst engineering colleague Professor Hari Balasubramanian, who, with his wife, were at the same hotel as I in Santiago - the Ismael Hotel.

Some resilience on my part was required, since as I was shampooing my hair, with a head full of lather, the hotel had a pipe break, and there was no water. This happened about 2 hours before my keynote. Resilience comes with being Ukrainian.

I have posted the slide deck of my keynote on the Virtual Center for Supernetworks website. In my keynote, I spoke about, among other work, recent research done with my Isenberg School of Management PhD student Dana Hassani and colleagues at the Kyiv School of Economics in Ukraine Oleg Nivievskyi and Pavlo Martyshev, which was published in the Journal of Global Optimization.

It was truly special to have my former Isenberg School of Management PhD student, Dmytro Matsypura, who is head of the Business Analytics Department at the University of Sydney in Australia come to my keynote as well as Professor Renata Konrad on WPI and Professor Moldovan of Romania.

Many thanks to IFORS for the incredible work on this conference! The conference website can be accessed here.

Thrilled and Honored to be Working with Colleagues in Ukraine

With Russia's war on Ukraine ongoing and resulting in tremendous suffering and loss of lives as well as destruction, one must do what one can to support Ukrainians and those fighting for their freedom and democracy.

As a daughter of Ukrainian WWII refugees, whose first language is Ukrainian, and, as an educator, the partnership between the University of Massachusetts Amherst and the Kyiv School of Economics (KSE) is forging outstanding connections across the miles during this very challenging period in history. The partnership is now supporting 15 Virtual Scholars in Ukraine, 9 of whom are placed with Isenberg School of Management faculty. 

I am thrilled and deeply honored to be working now with colleagues in Ukraine. I would like to specifically thank the Isenberg School Dean Anne P. Massey and the Director of the International Programs Office and Vice Provost for Global Affairs at UMass Amherst Kalpen Trivedi for their outstanding support in making this partnership a reality and having it flourish since its inception over a year ago! Kudos also to Provost Emeritus John McCarthy for his support and to all the members of the Task Force who worked on forging this partnership. Special thanks to the KSE Rector Tymofiy Brik for his great work in making this partnership happen and also for visiting us in person on May 3!

Below is a photo taken with Rector Brik and Provost Emeritus McCarthy after dinner on May 3.

Some of the research with colleagues in Ukraine is also engaging a PhD student of mine - Dana Hassani. At the forthcoming Dynamics of Disasters conference, which will take place July 3-6, 2023,  in Athens, Greece (and which I am also co-organizing), I will present our latest work, "Multicommodity International Agricultural Trade Network Equilibrium: Competition for Limited Production and Transportation Capacity Under Disaster Scenarios with Implications for Food Security," co-authored with Dana and with KSE colleagues Professor Oleg Nivievskyi and Dr. Pavlo Martyshev.

Information on this conference is available here. 

This work builds on our paper, "Exchange Rates and Multicommodity International Trade: Insights from Spatial Price Equilibrium Modeling with Policy Instruments via Variational Inequalities," which was recently published in the Journal of Global Optimization. That paper was presented at the PanOptic Conference in honor of Professor Panos M. Pardalos held March 9 and 10 in Gainesville, Florida.

We heard yesterday the good news that the above paper has been accepted for presentation at the INFORMS conference in Phoenix and Dana Hassani will present it.

And, with Professor Elena Besedina of KSE, I have co-authored a paper, "A Multicommodity Spatial Price Equilibrium Model with Non-Tariff Measures for Agri-Food International Trade."

In addition, Professor Myroslava Kushnir of the Ukrainian Catholic University in Lviv more recently joined our program and we are excited to be collaborating now with her on various supply chains of relevance in Ukraine in wartime.

Below, I have posted a group photo from the May 3 symposium at UMass Amherst which featured the Virtual Scholars from the Isenberg School and also those from the School of Social and Behavioral Sciences at UMass Amherst.

In the photo from l-r are: Professors Muzzo Uysal, Lauren McCarthy, Rector Brik, yours truly, Professors Ina Ganguli, Alicia Johnson, Vice Provost Kalpen Trivedi, and Professor Bogdan Prokopovych. More information about the Virtual Scholars and their Faculty Hosts at the Isenberg School can be found on this link.

This partnership has worked towards reducing brain drain from Ukraine, enhancing research as well as friendships, and has also provided important financial and emotional support. More such partnerships are needed to support higher education in Ukraine, now and during the recovery and reconstruction. 

A press release by UMass Amherst on the partnership is available here.
