The Mathematics for the Real World Conference in Odense - Kyiv was Outstanding and Inspiring

I am back from a whirlwind trip. Last week, I took part in my 4th conference of this summer and it was extra special - the Mathematics for the Real World Conference in Odense and Kyiv organized by the International Centre for Mathematics (ICMU) in Ukraine (the host in Kyiv) and the Center for Quantum Mathematics at the University of Southern Denmark (the host in Odense). I flew from Boston Logan to Copenhagen and then took a shuttle to Odense (and also back).

The event had outstanding speakers and even students from Ukraine as participants, now studying at universities in other countries. 

Last Wednesday was what I call a "perfect day" at the conference. It began with the Fields Medalist Maryna Viazovska delivering the plenary talk on "Formal and Informal Mathematics of Sphere Packing," followed by my plenary on "Networks, Supply Chains, and Variational Inequalities," with terrific Q&A. Additional great talks were by Mykola Maksymenko on "Quantum Computations in Practice" and Oleksii Kuchaiev on "Artifical Intelligence in Practice." The panel discussion on Maths-Driven Innovations with Anna Lysyanskaya, Maryna Viazovska, Jørgen Ellegaard Andersen, and me in Odense, and Jean-Pierre Bourguignon, streaming in, plus colleagues in Kyiv taking part, with Khrystyna Gnatenko moderating and with an introduction by Maria Vlasenko was so exciting that it lasted past 6PM.

I am grateful to the organizers: Khrystyna Gnatenko, Alexander Marynych, Volodymyr Minin, and Anna Lysyanskaya, and to Jørgen Ellegaard Andersen, and to Oleksandra Golovkova plus Maria Vlasenko and Maryna Viazovska for their hard work on making this unique conference a big success. Congratulations also to the International Centre for Mathematics in Ukraine - ICMU, which was founded only in 2022, a very tough year for Ukraine and the world, and to the Centre for Quantum Mathematics (QM) on their accomplishments.

And a big shoutout to all the wonderful students from Ukraine who joined us  plus an appreciation to Li Quan, who, at the lunch on Wednesday, when I mentioned chocolate, produced some that he had recently bought in Munich and shared it with all of us at our table. I am sure that new collaborations will come out of this great event.

Information on the conference can be found on the ICMU website: https://icmu.ua/en/events/applied-maths-2026

Those of you who have been following the news, would know about the multiday continuing bombing of Kyiv by Russia. The last two days of the conference our colleagues in Kyiv spent in a bomb shelter but they insisted that the conference continue. Their fortitude, dedication, and courage inspire me.

Thank you, also, to UMass Amherst for this news release: https://www.umass.edu/news/article/anna-nagurney-delivers-keynote-joint-odense-kyiv-conference-mathematics-real-world

I have posted my presentation on the Supernetwork Center website: https://supernet.isenberg.umass.edu/visuals/ICMULecture-Nagurney-2026%201.pdf

Thanks to all my students (present and past) and to all of my co-authors!

Looking Forward to Giving a Plenary Talk at the Mathematics for the Real World Conference Taking Place in Odense/Denmark and Kyiv, Ukraine

I received the invitation last December and quickly accepted it.

I am thrilled and honored to have been selected to deliver a plenary talk at the "Mathematics for the Real World" conference happening next month simultaneously in Odense, Denmark and Kyiv, Ukraine. 

Many thanks to the organizers: Khrystyna Gnatenko, Alexander Marynych, Volodymyr Minin, and Anna Lysyanskaya, and to the International Centre for Mathematics in Ukraine - ICMU, its Executive Director Masha Vlasenko and the ICMU Scientific Director Maryna Viazovska, and the Centre for Quantum Mathematics (QM) at Syddansk Universitet - University of Southern Denmark for spearheading this exciting conference. 

I'm enjoying preparing my plenary presentation: "Networks, Supply Chains, and Variational Inequalities." 

Maryna Viazovska, the 2nd female Fields Medalist (and it is great that the 3rd female recipient of this prestigious math award, Hong Wang, was announced yesterday), will deliver the plenary talk: "Formal and Informal Mathematics of Sphere Packing." 

I'm also looking forward to being a panelist on the panel: Maths-Driven Innovations, along with Jean-Pierre Bourguignon, Maryna Viazovska, Oleksii Kuchaiev, Mykola Maksymenko, and Tymofiy Mylovanov.

Our Paper on Integrated Crop and Cargo War Risk Insurance with Application to Ukraine is Published!

The front page of today's Sunday New York Times has an article on Odesa, Ukraine, which is painful to read. This very important port city for Ukraine for trade has been subject to relentless bombing for the past few weeks with even a silo of sunflower oil attacked and the oil spilling into the Black Sea. Residents of Odesa have had to suffer from the bombing, and shortages of water and electric power.

We are all connected. A wonderful colleague at the Odesa Law Academy, Borys Kormych, has been a Virtual Scholar through our global partnership between UMass Amherst and the Kyiv School of Economics (KSE) in two cohorts. In the most recent one, my Isenberg School of Management PhD student, Ismael Pour, and I have had the honor and pleasure of collaborating with him. We always worry how our colleagues, collaborators, and friends are doing in the illegal, horrific war perpetrated on Ukraine and Ukrainians.

An outcome of our collaboration  is the paper, "Integrated crop and cargo war risk insurance: application to Ukraine," that was published in the January 2026 issue of the International Transactions in Operational Research (ITOR): https://onlinelibrary.wiley.com/doi/10.1111/itor.70038?af=R A reprint of the paper can be downloaded here: https://supernet.isenberg.umass.edu/articles/IntegratedWarInsurance.pdf

Today the President of Ukraine Zelenskyy will be meeting with President Trump in Mar-a-Lago.  

Peace with security must return to Ukraine. 

After almost 4 years of the full-scale invasion by Russia, with billions of dollars of destruction and so much suffering and loss of lives, the war needs to end with the aggressor also paying for all the consequences. 

Our Paper is Published in the Latest Issue of the Ukrainian Analytical Digest Focused On: Recovery, Resilience, and Resources

This past week our paper, "Rebuilding the Crossroads of Ukraine: Bridging the Gap Between Damage, Recovery and European Aspirations," co-authored by Oleh Nivievskyi and Dmytro Goriunov of the Kyiv School of Economics (KSE) and me, was published in the latest edition of the Ukrainian Analytical Digest. The issue is focused on: Recovery, Resilience, and Resources.

It is especially thrilling that our paper is the lead article in the issue. The issue is an excellent one and we acknowledge the assistance and guidance of its Editor, Eduard Klein, throughout the reviewing process.

The full issue is available for free and can be accessed here: https://css.ethz.ch/publikationen/uad/details.html?id=/n/o/1/4/no_14_recovery_resilience_and_resourcesn

And, just over a month ago, we had the pleasure of hosting Oleh Nivievskyi in our UMass Amherst INFORMS Speaker Series and he spoke on our paper!

Working with Ukrainian colleagues has been a bright light in Russia's horrific, illegal war on Ukraine, which continues. To-date, we have had the honor of collaborating (and publishing) with colleagues at KSE, at the Ukrainian Catholic University (UCU) in Lviv, and at the Odesa Law Academy. Their courage and dedication to their research as well as hard work in sustaining higher education during wartime is incredibly inspiring. Such collaborations are an outgrowth of the outstanding global partnership between UMass Amherst and KSE established through a series of MOUs shortly after the full-scale invasion of February 24, 2022.  We acknowledge the great work of the UMass Amherst Office of Global Partnerships and the Senior Vice Provost for Global Affairs Kalpen Trivedi.

Proud to Have Had Our Work Presented at the Disaster Risk Reduction Conference in Kyoto, Japan

Last week, my collaborator, Professor Myroslava Kushnir of the Ukrainian Catholic University (UCU) in Lviv, presented our paper, "Social Network Analysis of Civilian Support Networks for the Ukrainian Military," at the The 10th IFIP WG5.15 Conference on Information Technology in Disaster Risk Reduction (itdrr) in Kyoto, Japan: https://lnkd.in/eAu3_qyN. 

The paper will be published in the conference proceedings. Myroslava was a Virtual Scholar in the outstanding global partnership between the University of Massachusetts Amherst and the Kyiv School of Economics (KSE),  thanks to the UMass Amherst Office of Global Affairs and the Isenberg School of Management, UMass Amherst.  I have been working with Myroslava for over two years now and it has been a pleasure to collaborate with her.

Myroslava, in the above photo, is standing with Professor Renata Konrad of the Worcester Polytechnic Institute (WPI), who presented a poster at this conference. Our collaboration with Professor Konrad produced a paper that was published in the ISCRAM, Münster, Germany, 2024 Proceedings: https://lnkd.in/eFkZ94nB

Myroslava very much enjoyed the conference as well as being in Japan. I have been to both Tokyo and Yokahama for conferences and had extraordinary experiences there and wonderful memories.

Myroslava returned safely back to the Ukrainian Catholic University, where she teaches. I would have loved to have gone to this conference in Kyoto but, with my teaching schedule and upcoming INFORMS conference in Atlanta (next week), I could not make it. I am very proud and happy that she went, after traveling a great distance,  and presented our paper. Thanks also to the reviewers of our paper for their helpful comments and suggestions!

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

Outstanding Presentation by Dr. Oleh Nivievskyi on Rebuilding Crossroads of Ukraine

Yesterday we had the honor and great pleasure of hearing Dr. Oleh Nivievskyi present at the Isenberg School of Management in the UMass Amherst INFORMS Speaker Series! Dr. Nivievskyi's seminar title was, "Rebuilding Crossroads of Ukraine: Bridging the Gap Between Damage, Recovery, and European Aspirations." Dr. Nivievskyi is a Full Professor at the Kyiv School of Economics (KSE) and a Siemens Research Fellow at the Freie University of Berlin. He is  a co-founder of the KSE Agro-Food Center.

His presentation was based on a paper, now in production in the Ukrainian Analytics Digest, which is edited by Eduard Klein, and which is co-authored with Dmytro Goriunov of KSE and me. We expect the paper to be published in an issue later this month.

Professor Nivievskyi had a few travel kerfuffles but made it to Northampton on Thursday via Amtrak from DC after flying from Europe. We picked him up at the train station and then had a lovely dinner at the Whately Inn al fresco.

He overnighted at the UMass Amherst Hotel and had a quick tour and meetings with students in the morning, followed by his outstanding presentation, and then lunch at The Commonwealth Restaurant.

It was wonderful to have a fabulous audience that included several exchange students from KSE plus our OIM Department Chair Professor Solak. Thanks to everyone for the great questions and discussions! It was thrilling to have two faculty from Amherst College, who are Ukrainian, join us for lunch.

The UMass Meet and Greet service provided a comfortable ride to the Springfield Union Station for his journey to NYC for some KSE business.

Along with my Isenberg PhD student, Dana Hassani, we had published several papers with Nivievskyi in such journals as Transportation Science, the European Journal of Operational Research, and the Journal of Global Optimization,  and a paper in the recent Dynamics of Disasters edited volume; see my recent post: https://annanagurney.blogspot.com/2025/07/working-with-colleagues-in-ukraine-is.html. It was very special that Nivievskyi could meet my PhD students in person, including co-author Dana.

We organized this event on short notice but one has to take advantage of opportunities. Having face to face engagements between scholars and students is very enriching education-wise and also personally!

Many thanks to the UMass Amherst Office of Global Affairs for the support of the partnership with KSE!

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.

Congratulations to the 2025 Shevchenko Emergency Fellows! Honored to Have Served on the Committee

Russia's war on Ukraine continues to rage and is now in its 4th year. Many Ukrainian scholars, writers, and artists have been deeply affected.

I'd like to thank the Shevchenko Scientific Society (abbreviated NTSh in Ukrainian) for funding its second cohort of  Shevchenko Emergency Fellows (SEF). The first cohort was announced in 2022 and the 2025 cohort of 50 Fellows has just been announced: https://shevchenko.org/grants-and-scholarships/sef-fellows-2025-announcement/. All the Fellows, their affiliations, and their projects can be found on the above link.

It was an honor to, again, serve on the SEF Selection Committee, with Mayhill Fowler as Chair and with committee members: Markian Dobczansky, Kateryna Ruban, Martha Kuchar, Orest Deychakiwsky, and Margarita Balmaceda. The committee worked very hard in evaluating the Fellowship recipients, with 50 awardees selected, each of whom has received $2,000, a six-month affiliation with NTSh-A, a shevchenko.org email address, and a public profile page. An according to the Society webpage: "Fellows are encouraged to participate in the intellectual life of the Society virtually through its events, roundtables, lectures, conferences, and publications, and by interacting with its members in the U.S."

The projects of the Fellows are fascinating and represent many different disciplines and regions of Ukraine, with 4 Fellows being outside of Ukraine. In the case of academics, many different universities in Ukraine are represented. 

Supporting Ukrainian scholarship and culture is critical during wartime and in the future.

We wish all the Fellows all the best on their projects during these very challenging times. 

We hope that donations will enable another round of SEFs in the not too distant future and we pray for peace and victory for Ukraine.

Working with Colleagues in Ukraine Is Inspiring

Since Russia's full-scale invasion of Ukraine on February 24, 2022, I have been deeply involved in supporting higher education there. I had already been quite active, due to my affiliation with the Kyiv School of Economics (KSE) as both a member of its Board of Directors (BOD) and its International Academic Board over several years, but, in March, 2022, my connections intensified since I was elected one of the four Co-Chairs of the BOD of KSE https://kse.ua/community/stories/board-of-directors/.  Shortly thereafter, my university - UMass Amherst - established a global partnership with KSE. The partnership included both a student exchange student program (very successful) as well as a Virtual Scholar in Residence Program to reduce brain drain from Ukraine. We have now had two sets of cohorts of Virtual Scholars and I have enjoyed working with several of the scholars.

My colleagues in Ukraine inspire me and I believe that the research that we have done together is strengthened through our collaborations.

I am honored and delighted that Professor Myroslava Kushnir from the Ukrainian Catholic University (UCU) in Lviv and I have had our latest paper accepted for presentation at the Information Technology in Disaster Risk Reduction Conference at Kyoto University https://itdrr.org/conference/itdrr2025/. Our paper, "Social Network Analysis of Civilian Support Networks for the Ukrainian Military," emphasizes that Russia’s war on Ukraine is not only a geopolitical conflict but also a humanitarian, ecological, social and economic disaster. Our study applies Social Network Analysis (SNA) to explore the interaction structure between civil society organizations (CSOs) and military units in Ukraine during the ongoing full-scale war. Dr. Kushnir has been a Virtual Scholar in both cohorts. Our first joint paper, "Civilian-Military Integration in Ukrainian Defense Supply Chain," co-authored with Renata Konrad of Worcester Polytechnic Institute, was published in the Proceedings of the International ISCRAM Conference: https://ojs.iscram.org/index.php/Proceedings/article/view/49

And just a few days ago, at the great EURO Conference in Leeds, UK, I presented a paper co-authored with my Isenberg School of Management PhD student, Ismael Pour, and Professor Borys Kormych of the Odesa Law Academy. The paper, "Integrated Crop and Cargo War Risk Insurance: Application to Ukraine," was recently published in the International Transactions in Operational Research (ITOR): https://onlinelibrary.wiley.com/doi/abs/10.1111/itor.70038 Professor Kormych had also been a Virtual Scholar in the two cohorts. 

And, with Virtual Scholar Pavlo Martyshev and Professor Oleg Nivievskyi of KSE, we have published 4 papers, along with my Isenberg School of Management PhD student Dana Hassani. I am very proud of this work. The papers that have appeared in journals are: 

"A Multiperiod Multicommodity Capacitated International Agricultural Trade Network Equilibrium Model with Applications to Ukraine in Wartime," Dana Hassani, Anna Nagurney, Oleg Nivievskyi, and Pavlo Martyshev, Transportation Science 59(1): (2025), pp 143-164,

"Multicommodity International Agricultural Trade Network Equilibrium: Competition for Limited Production and Transportation Capacity Under Disaster Scenarios with Implications for Food Security,"Anna Nagurney, Dana Hassani, Oleg Nivievskyi, and Pavlo Martyshev, European Journal of Operational Research 314(1): (2024), pp 1127-1142,

"Exchange Rates and Multicommodity International Trade: Insights from Spatial Price Equilibrium Modeling with Policy Instruments via Variational Inequalities," Anna Nagurney, Dana Hassani, Oleg Nivievskyi, and Pavlo Martyshev, Journal of Global Optimization 87: (2023), pp 1-30.

Plus, we have the following paper: "Quantification of International Trade Network Performance Under Disruptions to Supply, Transportation, and Demand Capacity, and Exchange Rates in Disasters,"Anna Nagurney, Dana Hassani, Oleg Nivievskyi, and Pavlo Martyshev, published 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 (2024), pp 151-179.

Dana Hassani has received 4 research awards (2 from the OIM Department and 2 from the Isenberg School) for his publications. These are significant recognitions.

I have written additional article with Professor Nivievskyi and am extremely proud of the paper, "Ukraine - Addressing the Domestic Crisis and the Effects of the War on Global Food Systems," which was published by the Pontifical Academy of Sciences: https://www.pas.va/en/publications/scripta-varia/sv154pas/nivievskyi.html

I have also worked with Professor Elena Besedina of KSE. She was a Virtual Scholar in the first cohort. The paper that we co-authored is: "A Multicommodity Spatial Price Equilibrium Model with Exchange Rates and Non-Tariff Measures for Agri-Food International Trade," Anna Nagurney and Elena Besedina, Operations Research Forum 4: (2023), 84.

My colleagues and collaborators in Ukraine have dealt with drones and missiles and losses of family members and friends and much too much time in shelters. They continue to teach and to conduct research under very challenging conditions. What they do to support their students and knowledge discovery in wartime is heroic. I thank them from the bottom of my heart and look forward to peace and prosperity for Ukraine and its freedom-loving citizenry.

Presented Our Integrated War Risk Insurance Paper at EURO in Leeds

The outstanding EURO 2025 conference in Leeds is now over and delegates have disbursed. Scientific conferences are essential to knowledge exchange and also to networking and building communities.

Visit of Dr. Kyrychenko from the Kyiv School of Economics (KSE) to UMass Amherst

This past week, we were delighted to have Dr. Kostyantyn Kyrychenko, the Vice Rector for International Cooperation at the Kyiv School of Economics (KSE), come to UMass Amherst. Those of you who have been reading my blog are aware of the global partnership between these two universities established shortly after Russia's full-scale invasion of Ukraine on February 24, 2022. 

It was a pleasure to have Dr. Kyrychenko join a group of us for lunch. At the delicious lunch at The Commonwealth Restaurant sponsored by the UMass Amherst Office of Global Affairs (OGA) even the one and only Associate Vice Chancellor Ken Toong stopped by! When I told our distinguished visitor from Ukraine that UMass Amherst had been voted as having the best college food 7 years in a row - he corrected me (thank you) - UMass Amherst has received this honor 8 times! Special thanks to Kimberly Stender and Claire Novotny of the Office of Global Affairs for the lovely time and to my great Isenberg School of Management, UMass Amherst colleagues, Professors Bogdan Prokopovych 🇺🇦 and Ina Ganguli, who also has an appointment in our Economics Department and who graciously shared the photo with Ken Toong in the collage below. It was extra special to also have exchange students from KSE join us.

I was touched by a lovely gift set that Dr. Kyrychenko presented me from Sumy, which is the city in eastern Ukraine that he is from and also where one of our exchange students is from. Kimberly Stender presented him with some gifts from the Office of Global Affairs and he gave her some KSE branded gifts. The conversations were wonderful and I am sure that they will continue. The exchange student program has brought 7 different students from KSE to UMass Amherst in the past two years and they have thrived on our beautiful campus. The students are fabulous ambassadors for Ukraine and their courage and work ethic inspire me.

We thank Dr. Kyrychenko for visiting us. The journey from Ukraine is quite long and I know that tomorrow he will be back for KSE Open Days!

Congratulations to Dana Hassani on Receipt of the 2025 Outstanding Doctoral Student Researcher Award at the Isenberg School!

On May 9, the Isenberg School of Management held its All School Meeting to wrap up the academic year. At the meeting, various awards were given out to faculty, staff, and doctoral students.

My Isenberg PhD student in Operations Management Dana Hassani, who was announced as the recipient of the 2025 Outstanding Doctoral Student Researcher Award, was, at that time, was en route to the POM Society Conference in Atlanta, so could not attend. I had blogged about this conference in previous posts.

So, this past Thursday, after the Isenberg PhD robing ceremony, the Director of our PhD Program, Dr. George Milne, presented Dana with the award plaque in our Business Innovation Hub.

Dana arrived at UMass Amherst in January 2022, after a delay in obtaining his visa. He has published 3 journal articles, and one book chapter, which is quite remarkable. And he has also been teaching this past academic year a required course, "Business Data Analysis," for our business undergraduates each semester. Dana is the lead author of the paper, "A Multiperiod, Multicommodity, Capacitated International Agricultural Trade Network Equilibrium Model with Applications to Ukraine in Wartime," co-authored with me, and Kyiv School of Economics (KSE) colleagues: Oleg Nivievskyi and Pavlo Martyshev, which appears in in the INFORMS journal Transportation Science,  vol. 59, no. 1, January-February 2025, pp. 143–164. He is also the co-author (second author) with the same co-authors as above of the paper, "Multicommodity International Agricultural Trade Network Equilibrium: Competition for Limited Production and Transportation Capacity Under Disaster Scenarios with Implications for Food Security," published in the European Journal of Operational Research, vol. 314, no. 1, 2024,  pp. 1127-1142. He is also a co-author, with the same authors as above of the paper, "Exchange Rates and Multicommodity International Trade: Insights from Spatial Price Equilibrium Modeling with Policy Instruments via Variational Inequalities," published in the Journal of Global Optimization, vol.  87, 2023, pp. 1-30.

Dana's book chapter, co-authored with the same team as his journal articles, "Quantification of International Trade Network Performance Under Disruptions to Supply, Transportation, and Demand Capacity, and Exchange Rates in Disasters," was published 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, 2024, pp. 151-179.

It is important to emphasize that there are 9 tracks in the Isenberg PhD Program so receiving this award is quite the achievement. And, Dana also got this award last year. He successfully defended his dissertation proposal a few months ago. I look forward to his successful PhD defense in the coming academic year. He has done excellent research focusing on agricultural supply chains and international trade under disruptions, including in Ukraine during wartime. It has been an honor to work with him and with colleagues at the Kyiv School of Economics. 

We Celebrated the Outstanding Exchange Students from the Kyiv School of Economics (KSE)

This is the second full academic year that exchange students from the Kyiv School of Economics (KSE) in Ukraine have been studying at UMass Amherst. The exchange program, during wartime Ukraine, was made possible because of a partnership established between KSE and UMass Amherst, under the leadership of the Vice Chancellor for Global Affairs Dr. Kalpen Trivedi.

Two of the KSE exchange students have been with us for two academic years and are now returning back to Ukraine. Two are staying on for another year and we expect additional ones to arrive in the Fall.

I invited the students for a special dinner in order to celebrate their accomplishments. The dinner was at The Inn at Boltwood in downtown Amherst.  The warm conversations covered much territory - the students' classes and great professors, friends made from Massachusetts and from around the globe, the award-winning UMassAmherst food, college sports (notably, UMass hockey), life in beautiful Amherst, and the differences between learning in the US and in Ukraine. Traveling thousands of miles from their homes and their families, the students: Asta Motrenko, Marharyta Nechytailo, Oleksandra Horusieva, and Karyna Lutsenko have achieved so much and have left a big imprint on all those who have had the pleasure of interacting with them. Thanks to Lorraine Martinelle of Marcomm at the Isenberg School for the lovely, informative article on the students: https://www.isenberg.umass.edu/news/three-years-later-isenberg-reflects-umass-amherst-partnership-ukrainian-institution

They students have spoken on university panels (thanks to UMass Amherst Student Chapter of INFORMS), been on Talk the Talk radio show, made the Dean's List each semester, took part (Marharyta as an analyst) in the amazing and very impactful Isenberg Undergraduate Consulting Group (IUCG) and even placed second on a team in a national Capital One competition. Songs have been created, produced, and performed in Amherst (Asta). Since two students are returning to Kyiv, with Ukraine still enduring war, now in its 4th year,  this made the evening also bittersweet. 

I am sure that the KSE exchange students will play an important role, through their education, experiences and friendships made, in the recovery and rebuilding of Ukraine. A big thanks to their professors, including those at the Isenberg School of Management, UMass Amherst, who have provided such outstanding courses and have mentored them. And, thanks to the top administrators: Provost Fouad Abd-El-Khalick, Vice Provost for Global Affairs Kalpen Trivedi, and Isenberg Dean Anne P. Massey for the support in the global partnership between UMass Amherst and KSE. 

Presentations of Our POMS Talks in Atlanta Have Been Posted: From Agricultural Trade to War Risk Insurance

Last week,  I was busy with events and the last week of the academic year, but my Isenberg School PhD students traveled to Atlanta to present our joint work at the POM (Production and Operations Management) Society 35th Conference. They had an outstanding time and also, thanks to Isenberg PhD alumna, Dr. Deniz Besik of the University of Richmond, enjoyed a delicious lunch at a Turkish restaurant. My former PhD student, now at the University of Portland, as a tenured Associate Professor, Dr. Min Yu, also joined them. Below is a collage of photos of my PhD students: Dana Hassani, Ismael Pour, and Samira Samadi, presenting plus a lunch photo.

Dr. Deniz Besik also presented on our work on food banks. Below is a graphic of the first slide of our four presentations.

The slide decks of the full presentations, which, in the case of my PhD students, were all based on recently published papers, can be found on the Supernetwork Center website:  https://supernet.isenberg.umass.edu/visuals.html Dana's presentation was based on a paper published in the INFORMS journal Transportation Science. Ismael's paper appeared recently in International Transactions in Operational Research, and both his and Dana's paper was co-authored with colleagues in Ukraine. Samira's paper, which was co-authored also with Ismael, appeared in the Journal of Nonlinear and Variational Analysis.

I am very lucky to have excellent PhD students (present and former).

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

I am a very lucky and proud Academic Mom. My 3 Isenberg School of Management, UMass Amherst PhD students will present our recently published papers at the POMS Conference in Atlanta, which overlaps with Mother's Day https://pomsmeetings.org/conf-2025/

Dana Hassani will present the paper, "A Multiperiod, Multicommodity, Capacitated International Agricultural Trade Network Equilibrium Model with Applications to Ukraine in Wartime," which was co-authored with colleagues at the Kyiv School of Economics: Oleg Nivievskyi and Pavel Martyshev, and published in the INFORMS journal Transportation Science: https://lnkd.in/eUC3PA3J.  Ismael will present the paper, "Integrated Crop and Cargo War Risk Insurance: Application to Ukraine," which was co-authored with Borys Kormych of the National University "Odessa Law Academy" and published just this morning in the IFORS journal International Transactions in Operational Research: https://lnkd.in/e-3MxaDY. Samira will present the paper, "A Variational Inequality Trade Network Model in Prices and Quantities Under Commodity Losses," that we co-authored with Ismael, and that was published open access in the Journal of Nonlinear and Variational Analysis: https://lnkd.in/eSuiqC_C. Support for co-authors in Ukraine was made possible through the outstanding partnership between the University of Massachusetts Amherst and the Kyiv School of Economics, thanks to the leadership of Vice Chancellor of Global Affairs Kalpen Trivedi and Isenberg School of Management, UMass Amherst Dean Anne P. Massey. 

Our presentations are ready!

Happy Mother's Day and Happy Conferencing! 

Three Papers Accepted in One Week!

My Mother always said that "good news comes in threes" and this week we certainly had some much appreciated good news.

My paper, "NetwORks and Policies: OR to the Rescue," which is based on the Blackett Lecture that I delivered at The Royal Society in London, England on December 5, 2024, thanks to The Operational Research Society, was accepted for publication in the Journal of the Operational Research Society. And, incredibly, I received the galleys of the paper yesterday (a Saturday) and they were in great shape. Below is the first page.

And, since the Blackett Lecture experience was so special I include a collage below made of photos from the event, with deep gratitude for all that took part.

Many thanks also to The Operational Research Society for posting my Blackett Lecture online on Youtube: https://www.youtube.com/watch?v=S-LsIEsi-m0

Also, we heard from the International Transactions in Operational Research that the paper, "Integrated Crop and Cargo War Risk Insurance: Application to Ukraine," that I co-authored with my PhD student Ismael Pour and Professor Borys Kormych of the Odesa Law Academy in Ukraine, was accepted for publication. We hope to receive the galleys soon. Professor Kormych is a Virtual Scholar in our terrific UMass Amherst - Kyiv School of Economics (KSE) partnership. He was in the first cohort and is also in the second cohort. You can read more about the Virtual Scholars and their Faculty Hosts at the Isenberg School of Management here: https://www.umass.edu/global-affairs/news/kyiv-school-economics-and-university-massachusetts-amherst-launch-second-round-virtual-scholar

We heard the good news shortly after Ismael Pour presented the paper in the doctoral seminar in Management Science that I am teaching this semester. We took the nice photo below with him and Yongdong Chen and Samira Samadi (both also PhD students in the seminar) after Ismael's presentation.

Ismael will present this paper at the POMS Conference in Atlanta next month.

Also, Samira (full first name is Samirasadat) and I got the paper, "Multicommodity Trade, Tariffs, and Rerouting," accepted in a very special volume: Convex and Variational Analysis with Applications: In Honor of Terry Rockafellar’s 90th Birthday. Panos M. Pardalos and Themistocles M. Rassias, Editors, Springer Nature Switzerland AG. This is a very interesting and timely paper, given the trade wars that are happening now in real time. It discusses the evasion of tariffs and impacts through rerouting, with minimum processing, except for repackaging/relabeling in other countries.

We are grateful to the Editors and reviewers of our papers.

President of the Kyiv School of Economics (KSE) Back at UMass Amherst

Yesterday, was a very busy, fascinating day with the return of Dr. Tymofiy Mylovanov to UMass Amherst. Mylovanov is the long-term President of the Kyiv School of Economics (KSE) in Ukraine. He has led this private university for over 3 years in war-time. Enrollment has tripled; many new programs have been started, including in engineering, an, through its KSE Institute, numerous timely white papers have been published, that are regularly cited in the media. KSE, even in wartime, has hosted many dignitaries and thought leaders. Mylovanov regularly speaks to the media, including CNN.

The day was blustery, with 60 mile an hour winds. Mylovanov told me about the turbulence on his flight from Reagan National in DC to Bradley Airport (our local airport) in Connecticut. Luckily, on the third attempt, the pilot landed the plane safely!

I had helped to organize his visit and talk, with assistance from the Office of Global Affairs and the UMass Amherst INFORMS Student Chapter. It was Mylovanov's 3rd visit to UMass Amherst since Russia's full-scale invasion of Ukraine on February 24, 2022. Shortly after that date, I was elected Co-Chair of the KSE Board of Directors but continue to serve on its International Academic Board. Very quickly UMass Amherst and KSE signed a series of MOUs and our global partnership was established.

Thanks to the Office of Global Affairs at UMass Amherst and its Director, Vice Provost Dr. Kalpen Trivedi, and Kim Stender for organizing the excellent lunch at The Commonwealth Restaurant with Provost Fouad Abd-El-Khalick, Dr. Trivedi, the Dean of Social and Behavioral Sciences Dr. Karl Rethemeyer, and Senior Associate Dean Lisa Masteralexis joining us. 

Since Mylovanov is having a big birthday in a few days, we surprised him with dessert and Happy Birthday and his name written out in chocolate.

Afterwards, we had a terrific, informal Meet and Great in the Elkins Room at the Isenberg School, which included the exchange students from KSE, some of our Operations Management PhD students, my OIM Department Chair, Professor Senay Solak, and Professor Bogdan Prokopovych.

We then, as a group, headed to the IALS building where Mylovanov gave the talk, "Future of Europe if Ukraine Loses," to a packed audience of students, faculty, and staff from UMass Amherst, and even from Amherst College and the community. The UMass Amherst INFORMS Student Chapter, whose President this year is my PhD student, Ismael Pour, did a fantastic job promoting this event. In fact, the announcement for Mylovanov's seminar was posted all week on the UMass Amherst homepage!

There was a great reception afterwards with delicious food and desserts.

We escorted Dr. Mylovanov back to his car and onwards to Bradley and DC.  Today, he flies to London and will visit several cities in different countries before his return to KSE and Kyiv.

Below is a collage of photographs from his very special visit.

Thanks to all who were able to join us!

2025 Panel with the Exchange Students from the Kyiv School of Economics in Ukraine

This was a very tough week, beginning with Monday, February 24, 2025, the 3rd anniversary of Russia's full-scale invasion of Ukraine,  followed by the visit of Ukraine's President Zelenskyi to the Oval Office in DC on Friday, February 28.

In the afternoon of February 27, we hosted a panel at the Isenberg School of Management with the exchange students from the Kyiv School of Economics (KSE) in Ukraine. I'd like to thank the UMass Amherst INFORMS Student Chapter and its President, Ismael Pour, for designing a nice flyer for the event and for handling the promotion and logistics.

Below is a collage of photos and the flyer.

It was an honor to moderate this panel with my colleague, Dr. Bogdan Prokopovych.

The slide deck of my presentation, with some background on the UMass Amherst - KSE partnership, which includes the student exchange program as well as a Virtual Scholar Program with scholars in Ukraine, can be found on the Supernetwork Center website: https://supernet.isenberg.umass.edu/visuals/KSEExchangeStudentPanel2025.pdf

Many thanks to all who came to support our four outstanding exchange students from Ukraine! Their work ethic, dedication, courage, friendliness, love of their homeland, and appreciation of all that UMass Amherst has to offer, are inspiring.
