As the Fall semester comes to a close, we’re excited to bring our community together for a relaxed end-of-semester gathering on Friday, December 12, beginning at 4:30 PM in ISOM Room N145. This event is open to all faculty, students, staff, and friends, and we’d be happy to have you join us.
We’ll have a mix of food to enjoy, including Ukrainian varenyky (pierogies), pizza, desserts, fresh fruit, and more. It’s a nice moment to step away from the end-of-term rush, connect with others, and celebrate the many activities and accomplishments of the semester.
Whether you’ve attended our events regularly or this would be your first time joining us, we’d love to see you there!
Below is the event poster with all the details. Looking forward to sharing the afternoon with you!
On Friday, November 7, our chapter came together for a cheerful celebration of two major recognitions from the 2025 INFORMS Annual Meeting in Atlanta: the Cum Laude Award for our Student Chapter and the President’s Award received by Professor Anna Nagurney. It was a great way to wrap up an exciting week for our community.
The celebration table was filled with delicious refreshments, including muffins, croissants, fruits, and a basket of chocolates kindly brought by Professor Nagurney. Everyone gathered around, talked, laughed, and enjoyed a relaxed morning before we cut the cake and continued the celebration.
We were also very happy to welcome Professor Arzum Akkas, who joined us for the gathering and shared in the celebration.
We would like to give a big thank you to last year’s Chapter President, Ismael Pour, for his leadership, and all of last year’s officers for their hard work that contributed to earning the Cum Laude Award. And a special thank you to our faculty advisor, Professor Anna Nagurney, for her constant support, guidance, and encouragement, which continue to strengthen our chapter year after year.
To wrap up, we took a group photo with both awards to mark the moment and thank everyone who supports the chapter.
The 2025 INFORMS Annual Meeting in Atlanta was memorable in more ways than one. While we had an exciting lineup of student presentations that showcased the strength and diversity of our research community, which we shared in an earlier blog post, this year stood out for an especially meaningful reason: we returned home not with one, but two major honors that made the conference truly unforgettable for us.
We are thrilled to share that Professor Anna Nagurney, our faculty advisor, received the INFORMS President’s Award, one of the highest distinctions in our field. This award recognizes individuals whose work has made exceptional contributions to society through operations research and management science (OR/MS). Professor Nagurney’s career has been defined by groundbreaking research, dedicated mentorship, and a deep commitment to making the OR/MS more inclusive and impactful, a legacy that continues to inspire us all. Celebrating this achievement on October 26, 2025, at the INFORMS Awards Ceremony at the Omni Hotel in Atlanta, alongside colleagues, alumni, and friends, made the moment even more special.

In addition to this remarkable recognition, the UMass Amherst INFORMS Student Chapter was honored with the Cum Laude Award at this year’s Student Chapter Award Ceremony, which took place on the evening of October 27 at the Omni Hotel. This award celebrates student chapters that demonstrate consistent engagement, leadership, and commitment to the OR/MS community. We’d like to extend a heartfelt thank you to our former Chapter President, Ismael M. Pour, whose leadership over the past year played a vital role in this achievement. We’re also grateful to the entire team of 2024–2025 chapter officers for their creativity, hard work, and collaboration.

To mark these special achievements, we’re hosting a Celebration Gathering on Friday, November 7, at 10:00 AM in ISOM Room N135. We warmly invite all faculty, students, and chapter members to join us for refreshments as we celebrate, catch up, and enjoy the excitement of this memorable INFORMS experience together.
It has only been a few days since the 2025 INFORMS Annual Meeting concluded in Atlanta, but the excitement and energy of the event remain with us in Amherst.

On Friday, September 19, 2025, the UMass Amherst INFORMS Student Chapter had the privilege of hosting Dr. Oleh Nivievskyi, Professor of Economics at the Kyiv School of Economics (KSE) and Siemens Research Fellow at the Free University of Berlin. Dr. Nivievskyi, a leading researcher in agri-food products, factor markets, and value chain analysis, delivered a timely and engaging presentation titled “Rebuilding Crossroads of Ukraine: Bridging the Gap Between Damage, Recovery, and European Aspirations.”
Pre-Talk Gathering
The day began with a warm pre-talk chat in Room N220 of the Business Innovation Hub from 9:00 to 10:15 AM. Dr. Nivievskyi met with our faculty advisor, Professor Anna Nagurney, along with PhD candidates Dana Hassani, Ismael Pour, and our chapter president, Samira Samadi. The discussion centered on global agri-food products, supply chains, and networks, allowing students to share their own research and gain valuable insights from Dr. Nivievskyi and Professor Anna Nagurney.
The Presentation
From 11:00 AM to 12:30 PM, Dr. Nivievskyi delivered his talk in Isenberg Room 111. Our new president, Samira, provided a brief introduction to Dr. Nivievskyi’s background, and then he was warmly welcomed by Professor Anna Nagurney. The audience also included Professor Senay Solak, Chair of the OIM Department, chapter officers, and three Ukrainian exchange students currently studying at UMass Amherst as part of the partnership between UMass Amherst and KSE: Oleksandra Horusieva, Viktoriia Baliuk, and Karyna Lutsenko.
In his presentation, Dr. Nivievskyi reflected on the immense impact of the ongoing war on housing and infrastructure. He noted that nearly one-fifth of Ukraine’s territory remains under occupation, with the scale of economic and infrastructural damage already surpassing the country’s 2024 GDP. Despite these challenges, Ukraine has begun the process of rebuilding, with modest but meaningful progress made in restoring parts of its housing and infrastructure. He emphasized that moving forward with reconstruction and recovery will require close coordination between Ukraine, its partners, and donors, and above all, a careful balance between rapid recovery efforts and sustainability standards in accordance with EU legislation.
Q&A
The talk was followed by a lively discussion with the audience. Questions reflected the broad scope of issues facing Ukraine, including the scale and timeline of reconstruction, the long-term ecological impacts of war, and the academic landscape in Ukraine.
Refreshments were provided, including coffee and muffins, and the atmosphere was made even more special when one of our chapter officers, Yukti Kathuria, brought a tiramisu to celebrate her birthday.
Following the presentation, we, along with Professor Anna Nagurney and two of the Ukrainian exchange students, hosted Dr. Nivievskyi for lunch at the Commonwealth Restaurant at UMass Amherst. We were also joined by two colleagues from Amherst College, Professor Nataliia Bychkova and Professor Myroslav Kryven, making it a truly enjoyable and memorable gathering.
Thank You
We sincerely thank Dr. Nivievskyi for kindly accepting our invitation and sharing such timely and insightful perspectives during this critical period for Ukraine. We are also grateful to Professor Anna Nagurney, our faculty advisor, for her continued guidance and support in organizing the event. Finally, we thank the OIM faculty, chapter officers, and exchange students for making this event so memorable.
We invite you to join us for more exciting events at UMass Amherst, with our next event being the 2025 INFORMS Annual Meeting Tune-Up. We look forward to seeing you there!
