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!

Honored to Have Reached Over 25,000 Citations on Google Scholar

I was my PhD Dissertation Advisor's  (Stella Dafermos's) first PhD student at Brown University. She was a trailblazer and left an incredible scholarly legacy although she passed away at the age of 49.

Somehow, with effort, luck, passion, and serendipity, I have managed to build a wonderful collaboration network with students (past and present) as well as researchers around the globe. For all my collaborators, I am deeply grateful.

And, as a female scholar, I think it is meaningful to have reached the milestone of over 25,000 citations to my work on Google Scholar. The full list of my publications, as well as my collaborators over the years,  can be found on my Google Scholar page: 

https://scholar.google.com/citations?user=ecFsBp0AAAAJ&hl=e

It is interesting that my two most highly cited publications are the first two books that I wrote, one with a former PhD student of mine, now Professor at SUNY Oswego, Dr. Ding Zhang. And, my most highly cited journal paper, published in Transportation Science, is a translation from German to English of the famous Braess (1968) paradox paper. That paper was co-authored with Professor Dietrich Braess and my former PhD student, now Professor Tina Wakolbinger of the Vienna University of Economics and Business. And, in 2002,  along with Professor Ding Zhang, and his wife (also a former PhD student of mine),  SUNY Oswego Professor June Dong, we published the paper, "A supply chain network equilibrium model," in Transportation Research E, which is my 4th most highly cited work.

Many thanks to all the researchers and scholars who cite our work!

Doing research (and having it make some impact) is the greatest reward but it is nice also to have the work acknowledged, read, and cited.

Congratulations to My PhD Student, Dana Hassani, on His Outstanding Doctoral Teaching Award

Last Friday, we had our end of the academic year All School Meeting at the Isenberg School of Management at which milestones were celebrated, announcements made, and both faculty and doctoral students were recognized for their professional contributions.

It was wonderful to see Dana Hassani, one of my PhD students in Operations Management at the Isenberg School, receive the 2026 Outstanding Doctoral Teacher Award. Dana has been in our doctoral program since late January 2022.  I enjoyed writing the nomination letter for Dana for this award and thank the Selection Committee for their hard work.

The award was presented to Dana by Associate Dean and Isenberg PhD Program Director Fousseni Chabi-Yo. Dana, for several semesters now, has taught the required course, OIM 240 - Business Data Analysis, for our undergraduates.  OIM 240 is a math heavy and technical course, which can become boring or  confusing for students. Dana reviews core course concepts multiple times to  ensure that every student has a strong grasp of the material. He also integrates lectures with real-world examples tailored to students’ interests, highlighting the applications of the content and making concepts more engaging.

Dana has shared with me how he regularly uses datasets from the  sports industry (e.g., NBA and WNBA franchises and soccer clubs) or social  media platforms. Students very much appreciate Dana’s extra effort, with many  reaching out after class to discuss the applications in more depth.

Excellent teachers can also be great researchers. Dana was recognized by the Isenberg School with the Outstanding Doctoral Student Research Award both in 2025 and in 2024. Dana has had 3 journal articles published and 1 book chapter and recently submitted another paper to a journal.

And, after the All School Meeting, was our Barbecue for Graduating Seniors, right outside of the Isenberg School.

I thank Professor Muzzo Uysal for taking the photo below before we headed out to eat and chat and meet with our soon to be graduates.

It is important to celbrate wonderful students and their achievements as they work towards their goals. Dana hopes to become a professor soon.

Delighted that Our Paper on Fresh Produce Trade and "Choke Points" is Published in EJOR!

The three of us worked very hard on this paper, "Fresh Produce Spatial Price Equilibrium on General Networks: Capturing Commodity Quality Deterioration Through Endogenous Transportation Time Delay Functions with Capacities," and it took three revisions (a record for me, I must say) before acceptance. My co-authors on this paper are Samirasadat "Samira" Samadi, who is one of my PhD students, and Professor Deniz Besik of the Robins School of Business at the University of Richmond.

The paper was published in a volume of the European Journal of Operational Research (EJOR) this past week, which was extra exciting since it also was the last week of classes of the academic year at UMass Amherst!

The link to the journal publication of the article is here: https://www.sciencedirect.com/science/article/abs/pii/S0377221726003759.

The work was inspired by many challenges associated with fresh produce transportation and quality of the commodities because of issues such as drought as in the Panama Canal and now the essential shutdown of the Strait of Hormuz because of the war on Iran. We capture endogeneous transportation delays due to capacity reduction on links and the impact on quality of fresh produce as it travels from supply markets to demand markets. The case study in the paper is on the global trade of bananas, a nutritious and very popular fruit, which is also important for food security. We also propose commodity quality trade network performance measures, supply-based, demand-based, and network-based, that can be applied for an individual commodity or across all commodities.

We are grateful to the EJOR Editor, Professor Mike Yearworth, who handled out paper, and to the reviewers for their comments and suggestions. My co-authors and I very much believe in the relevance and importance of the research that resulted in this paper.

Magnificent OIM Awards Celebration 2026

On April 20, 2026, my Operations and Information Management (OIM) Department at the Isenberg School of Management at UMass Amherst helds its Awards Celebration event.

A big CONGRATULATIONS to ALL the amazing students that were recognized and to the recipient of the OIM Distinguished Alumni Award Paul Cichocki! The awards celebration, which included a delicious banquet meal at The Inn at Boltwood in Amherst, was lovely - with expert organization, thanks to the Department Chair Professor Senay Solak, the Associate Department Chair Professor Michele Burch, and our great Office Manager Samantha Whittle. 

Congratulations to: the RSM U.S. Foundation Consulting Scholarship Recipients: Iris Cabral and Kamila Velez; The NCG Operations and Information Scholarship Recipient: Wendy Zou, and to The Nagurney Scholarship Recipient: Campbell Hatcher. Bravo to the Isenberg Senior Leadership Award Recipient: Gowri Vellanki and to Spencer Zbitnoff on his Isenberg Academic Excellence Award. The OIM Exceptional Impact Scholarship Recipients are: Reese Barnett, Suzanne Patti, Alfonso Alvarez Ribeiro, and Josie Wu! Congratulations to all the OIM Elevate Scholarship Awardees: Darrius Lupo, Ryan Bonia, and Carolin Zorrilla We also recognized two PhD students with the OIM Elevate Scholarship: Yue Xue, who is pursuing her doctorate in Information Systems, and Solmaz Abbaspour, who is pursuing hers in Operations Management. 

Many thanks to the OIM Faculty Scholarship Committee Members: Professors Susan Boyer, Ying Liu, and Shirley Shmerling. Many of the faculty, students, and their supporters lingered after the ceremony as we basked in the warmth of this truly special academic community. Best to all our students as they pursue their dreams!

This was the third time that my department held such an Awards Celebration and it is one of our favorite events of the academic year. It was also very special to have Campbell Hatcher receive The Nagurney Scholarship, which my husband and I established. Campbell wrote us a lovely letter a while back. She is majoring not only in OIM but also in Sport Management and, after her graduation next week, will be joining Kerry in Wisconsin. Her work ethic and engagement in so many activities, including mentoring ones, while working about 25 hours a week are inspiring.

Outstanding Guest Lecture by Mr. Seth Thayumanavan on Biotech in My Humanitarian Logistics Class

Last Thursday, I was delighted to welcome Mr. Seth Thayumanavan to my Humanitarian Logistics and Healthcare class at the Isenberg School of Management. His guest lecture was on the biotech industry, with a focus on background for the oncology startup that he co-founded with his father, Distinguished University Professor Thai Thayumanavan.  The name of the company is Nalam Technologies. 

The guest lecture was of great interest to my students in the class, who come from the Isenberg School, the Riccio College of Engineering at UMass Amherst, and also its School of Public Health.

His  presentation demonstrated the great passion that he has for the very important work of Nalam Therapeutics and its team. The students were captivated by the presentation that discussed the story of pharmaceutical cancer therapy and, in particular, targeted delivery systems to make cancer treatment safer and more effective plus the importance of the 4Ps: patients, payers, providers, and policy makers and the challenges associated with clinical trials and venture capital. The students appreciated Mr. Thayumanavan sharing his experiences from the valuable coursework at UPenn to the various positions that he has held. He highlighted that a career path need not be “linear” as well as the great value of networking, which I very much appreciated and agree with!

His presentation generated so many questions – always a sign of immense interest from the audience. I continue to receive comments from students who were both educated and very impressed by the guest lecture and work. We presented Mr. Thayumanavan with a framed Professor for a Day certificate, which had been signed by the Isenberg Dean Anne P. Massey!

Having expert practitioners speak to students provides for a very enriching educational experience.

I wish Nalam Technologies much success in their important work for humanity.

Thanks to Dr. Les Servi for Speaking in Our UMass Amherst INFORMS Speaker Series

On April 10, 2026, we had the honor and pleasure of having Dr. Les Servi speak in our UMass Amherst INFORMS Speaker Series. We were very excited to have Dr. Servi back at UMass Amherst. 

The title of his presentation was: “Identifying Critical Nodes in Mission Systems: An Operations Research Framework.” 

Dr. Les Servi is an Operations Research Scientist and former Chief Scientist for Cyber Operations Research at The MITRE Corporation. Earlier, he conducted research at MIT Lincoln Laboratory, Bell Laboratories, and GTE Laboratories (now Verizon), and spent a sabbatical year as a visiting scientist at Harvard University and MIT.  He has served as an Associate Editor for the journals: Operations Research, Management Science, and the INFORMS Journal on Computing. He is also  a MORS Fellow, an INFORMS Fellow, and served six years on the INFORMS Board of Directors. Dr. Servi is an INFORMS VP Chapters and Forums Board member.

Dr. Servi's book, "Mission Dependency Network Analysis," was published by Springer in 2026 and he kindly presented me with a copy. It was nice to see one of my papers with Patrick Qiang cited therein.

We had a great discussion after his presentation and at lunch. Many thanks to the INFORMS Student Chapter for doing such a nice job in publicizing his presentation - the announcement even made the UMass Amherst homepage with special thanks to the Chapter President Samira Samadi.

And, after the delicious lunch at the UMass Commonwealth Restaurant, Dr. Servi was off to Logan Airport to catch a flight to DC for the INFORMS Analytics Conference, where I joined him on Sunday!
