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.

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!

Our Spatial Price Network Equilibrium Paradox Paper is Published

It was thrilling to see our paper, "A Spatial Price Network Equilibrium Paradox," published this past week in the Springer journal Optimization Letters!

The paper I co-authored with Ladimer S. Nagurney and Ismael Pour, who is one of my PhD students at the Isenberg School of Management. The work builds on the famous Braess Paradox and reveals through numerous examples that: the addition of a new route from a supply market to a demand market may result in the supply price being lowered; the route costs being increased, and the demand price (the price that the consumers pay) also being increased relative to their values prior to the route addition. This result shows that there could be negative effects for both producers and for consumers and is especially relevant to the case of agricultural commodities. Hence, farmers may suffer in terms of lower prices for their products, and consumers in terms of higher prices that they pay! It is, hence, critical to investigate the impacts of the supply chain network topology, from a network design perspective, that includes the route topology.

This paper was first presented at the conference in Halkidiki in honor of Professor Panos M. Pardalos:

Ismael also presented the paper at the INFORMS Annual Meeting in Seattle last Fall and the slide deck can be downloaded here: https://supernet.isenberg.umass.edu/visuals/INFORMS2024-Presentation-NPS.pdf

The paper went through two revisions and can be accessed through the Springer journal website:

https://link.springer.com/article/10.1007/s11590-025-02244-y

We have done a lot of research on the Braess Paradox and even hosted the visit of Professor Dietrich Braess when I was a Science Fellow at the Radcliffe Institute for Advanced Study at Harvard University.

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!

Welcoming my New PhD Student to the Isenberg School of Management

It has been a dynamic first two weeks of the new academic year at UMass Amherst! I have been busy teaching my Transportation & Logistics class at the Isenberg School of Management and also with PhD comprehensive exams (3 for our Operations Management (OM) PhD students, 2 of whom are my students) plus many additional meetings.

A highlight of a new academic year is always meeting new students.  I was delighted to meet my new OM PhD student, Sarvagya Jha, who is from India. He joined me and my three other PhD students: Dana Hassani, Samira Samadi, and Ismael Pour, in my office. I then took the photo below next to my framed mathematics academic genealogy tree, which, through my PhD advisor at Brown University Stella Dafermos, goes back to James Maxwell, Isaac Newton, and Galileo Galilei, which is quite inspiring, I must say. The academic genealogy was presented to me by my former PhD student Dong "Michelle" Li, who is now a tenured Associate Professor at Babson College in Wellesley,  MA.

You can read more about my academic genealogy on my blog here: https://annanagurney.blogspot.com/2015/08/the-academic-family-tree-going-back-to.html

Good luck to all students on the new academic year!
