Deeply Honored to Have Been Selected to Deliver the 2024 Blackett Lecture at the Royal Society in London

You probably remember the day that you received some wonderful news and also the day that you received sad news.

This post is about the former.

I was at a conference in Kalamata, Greece in honor of the 70th birthday of Panos M. Pardalos last summer when the great news arrived. I had been selected by The Operational Research (OR) Society to deliver the 2024 Blackett Lecture at the Royal Society in London. Honestly, as I was reading the letter, the tears started to flow since I was so touched that my hard work was being recognized. 


Patrick Blackett, after whom the lecture is named, was the founder of  OR in the United Kingdom. In the US, we, typically, say "Operations Research." He was also awarded a Nobel Prize in physics.

The abstract of my lecture as well as a link to registration can be found here.

The letter from The OR Society, signed by the Executive Director Seb Hargreaves and by the President of The OR Society, Gilbert Owusu, is below.


I have been enjoying preparing my lecture, which will give a panoramic view of OR and policies from tolls for congested urban transportation networks to tariffs and quotas for agricultural supply chain networks. I will be bringing in a lot of personal experiences as well.


I am thrilled that there will even be guests from New England coming.

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 Outstanding INFORMS Conference in Seattle!

Last week I had the pleasure of taking part in the INFORMS conference in Seattle, which took place October 20 through October 23. It was a whirlwind conference since my research group had 5 presentations. I gave an invited talk on a paper on defense critical supply chain networks and labor, which was recently published in the Handbook of Management of Threats. Thanks to Shima Mohebbi for inviting me to speak in her game theory session. My 3 PhD students also presented papers. Dana Hassani spoke on our recent paper, now published online in the INFORMS journal Transportation Science, and co-authored with Kyiv School of Economics colleagues Oleg Nivievskyi and Pavlo Martyshev. Samira Samadi spoke on our work with my PhD student Ismael Pour on spatial price equilibrium models with commodity losses. And two days after her presentation in Seattle, the paper was published! Ismael delivered a paper co-authored with Ladimer S. Nagurney and me on a spatial price network equilibrium paradox. For both Samira and Ismael it was their first INFORMS conference!

The panel that I spoke on was a "Committee's Choice" one and it was a great honor to join fellow panelists Tom Magnanti and Linus Schrage, both of whom need no introductions. Chris Ryan was an excellent moderator.  The panel was on What Our Past Can Tell Us About Our Future. I took the perspective of Herstory.


There were editorial board meetings for several journals that I serve as an Associate Editor of  (Journal of Global Optimization and Optimization Letters plus the International Transactions in Operational Research)  - it was great to see fellow editorial board members.

Another highlight was having my Labor and Supply Chain Networks book and the Handbook for the Management of Threats displayed at the Springer booth at the Exhibit Hall.

I thoroughly enjoyed talks and  the INFORMS Fellows lunch. 3 of my nominees got elected this year and there were 12 Fellows, so it was extra special to celebrate with them - Hani S. Mahmassani, Celso Ribeiro, and Grazia Speranza. I also very much enjoyed the WORMS lunch.

Several former PhD students, who are successful professors now, joined me: Pritha Dutta and Grace Ke, and Dmytro Matsypura, who traveled all the way from Sydney, Australia. It was delightful to also see Patrick Qiang.

It was terrific to have the UMass Amherst INFORMS Student Chapter recognized with the Magna Cum Laude Award.

The below collage of photos captures some of the highlights.


INFORMS organized so many additional meetings and networking events at this conference, which I also appreciated. We were kept very busy but the conference was very enjoyable with over 7,300 registrants from around the globe! More info on this conference.

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!

Congratulations to the Radcliffe Institute for Advanced Study at Harvard University on its 25th Anniversary!

The Radcliffe Institute for Advanced Study at Harvard is truly a very special place. I had the great honor of being a Science Fellow in 2005-2006, just a few years after its founding in 1999. It was an incredible year for me with wonderful new friendships made, the writing of my Supply Chain Network Economics book, and many experiences plus collaborations, including with the now Dean of SEAS, David Parkes. Radcliffe also supported my collaborator Patrizia Daniele of Catania, Italy, and she wrote her Dynamic Networks book while at Radcliffe. She also worked with me and Parkes. The Science Fellows were housed at Putnam House and there were engineers, physicists, mathematicians, and computational linguists with us. Radcliffe, at that time, had several buildings for the Fellows. We joined one another for delicious lunches and talks as well as receptions and special events. Since that fabulous year, I have been back to visit many times, and have been a Summer Fellow at Radcliffe twice. I also co-organized with David Parkes an Exploratory Radcliffe Seminar focusing on dynamic networks. Radcliffe now has its own quad and all Fellows are housed in the same building. I love the garden and fountain and there are also often art exhibits.

So, when I heard that Radcliffe would be celebrating its 25th anniversary on September 26 and 27, I had to join, despite a busy teaching schedule, office hours, hosting of  a speaker, and also an All School Meeting of the Isenberg School! To-date, there have been about 1,200 Radcliffe Fellows. 


On September 26, Radcliffe, to kick off its 25th anniversary, hosted an outstanding panel. The session began with introductory remarks by Radcliffe Institute Dean Tomiko Brown-Nagin, who shared some of the history of the Radcliffe Institute and also noted her predecessors as Dean. When I was at Radcliffe, Drew Gilpin Faust was the Radcliffe Dean, and I told her that she would become the next President of Harvard and she did the year after my Fellowship year! The Science Dean my year was the outstanding, very inspiring computer scientist Barbara Grosz.  Brown-Nagin also shared a terrific video of an astronomy discovery by Radcliffe Fellows, which included Alyssa Goodman, whom I have met.

The panel, consisting of two Nobel laureates in Economic Sciences, Claudia Goldin and Oliver Hart, both of whom had been Radcliffe Fellows,  was moderated by the present President of Harvard, Alan Garber. Claudia was a Radcliffe Fellow the same year that I was and here you can see the full 2005-2006 list: https://news.harvard.edu/gazette/story/2005/06/radcliffe-names-2005-06-fellows/

President Garber was an outstanding moderator and I was very impressed by his delightful sense of humor! He reminisced about carrying punch cards across campus, as a student, and always being worried about dropping them. When Claudia spoke, she brought back so many memories of that magical year. She mentioned Geraldine Brooks and her husband Tony Horwitz (who sadly passed away not that long ago) and said that Claudia Olivetti became her best friend. Coincidentally, Claudia is Italian as is my collaborator, Patrizia Daniele. I recall fondly many conversations over lunch together about Berlusconi. Claudia spoke beautifully about what economics is and noted that there are too few females majoring in economics. Male undergrads think econ is finance, so they major in it whereas females also think that econ is finance, so they shy away from it. She emphasized that economics is about people! That reminded me of the essay that I wrote for ORMS Today: In the End, It's All About People!   Oliver Hart, when asked about the influence of technology on his work, said that, as a theoretical economist, he just needs a yellow pad and pencil. He said that he does use technology to communicate with his collaborators but misses the trips that he would take to collaborate face to face. Claudia said that having access to AI would have saved her lots of drudgery type work.

Both Claudia and Oliver are so passionate about their research and that was incredibly energizing and inspiring to hear. 

Information on the Radcliffe Institute for Advanced Study and its Fellowship Program can be found here.

And here is a post on the 10th anniversary of Radcliffe in which I have several photos from our Fellowship year and in the photos are several individuals noted above.

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.

Outstanding Future BA (Business Analytics) Prof Workshop at the University of Iowa

I recently returned from the Tippie College of Business at the University of Iowa. I was there to give an invited talk on research at the 3rd Future BA (Business Analytics) Workshop. Many thanks to Professor Ann Melissa Campbell for inviting me and congratulations to her and to her workshop co-organizers Professors Kang Zhao and Beste Basciftci on the success of the workshop!

There had been 80 applicants with 28 selected and participating with advanced PhD students and postdocs from many universities taking part including: UC Berkeley, Virginia Tech, Purdue, Clemson, University of Oklahoma, University of Buffalo, Harvard, MIT, and UMass Amherst.  It was my first time in Iowa and it was great to see the faculty and to also hear from the other invited speakers: Professor Tallys Yunes, who spoke on teaching, and Professor Bin Gu, who also spoke on research. 

Below is a photo that was taken of the group. It was quite remarkable that I had met several of the PhD students previously. 


I was also thrilled that my PhD student, Dana Hassani, took part. It was great to hear him give the elevator speech on his research and to hear from the others.



What impressed me was the enthusiasm and passion of the participants for their research, which I found uplifting and inspiring. 

The workshop kept us all very busy with the presentations, nice lunches and coffee breaks, networking sessions, and a dinner at a winery.

We could not resist taking a few more photos and the smiles on everyone's faces show how rewarding this workshop was.



I wish all those who took part best of luck on their research and completing their dissertations, if they have not done so, plus successful academic job interviews!

I was very touched by the number of nice email messages I received from the PhD students and participants - they were very heartwarming and I appreciate the politeness and the reaching out.

This group has established a very nice and supportive network and I warmly thank Professors Campbell, Zhao, and Basciftci. It was also terrific to hear from Professor Barrett Thomas and to see Professor Thiago Serra, who has just joined the Tippie Business Analytics faculty after spending 5 years at Bucknell University.
