News Coverage on Our Latest Research

Real world events inform the research of my group at the Supernetwork Center at the Isenberg School of Management, that I founded in 2001 and continue to direct. 

Since the onset of the COVID-19 pandemic, we have continued to model and solve a spectrum of supply chain network problems that have been affected by various disruptions, which now, sadly, for almost 2 years, have also included major disruptions to agricultural trade caused by Russia's full-scale war on Ukraine. Our research, documented in journal articles and book chapters, has continued to quantify the impacts of labor shortages and security issues and blockages associated with transportation, production capacity limitations, along with the repercussions of Russia pulling out of the Black Sea Grain Initiative. We have also investigated the impacts of numerous trade policies from tariffs to quotas and have been heavily focusing on agricultural and food supply chains and associated food insecurity.

Our research on agricultural supply chains and international trade has been enriched by our collaborations with scholars in Ukraine, through the unique, outstanding partnership between UMass Amherst and the Kyiv School of Economics (KSE) that I have blogged about.

It is very much appreciated when the research that we are involved in gets attention from the news media. 

UMass Amherst issued this release on the paper, "Ukraine – Addressing the domestic humanitarian crisis and the effects of the war on global food systems,"  that I was deeply honored to contribute to and which was presented by my KSE colleague, Professor Oleg Nivievskyi, at the Vatican in May at the Workshop on Food and Humanitarian Crises. The paper can be directly accessed here.

Also, the University World News published a very moving article by Nathan M. Greenfield: "Partnership with US scholars helps to keep Ukraine HE alive." 

In the article,  Greenfield notes our paper, "Multicommodity international agricultural trade network equilibrium: Competition for limited production and transportation capacity under disaster scenarios with implications for food security, "  just published in the European Journal of Operational Research and done with my Isenberg School PhD student Dana Hassani and KSE scholars: Professor Oleg Nivievskyi and Dr. Pavlo Martyshev. 

In addition, the article in University World News discusses the recent paper I wrote with KSE Professor Elena Besedina, "A multicommodity spatial price equilibrium model with exchange rates and non-tariff measures for agri-food international trade," which was published in Operations Research Forum.

Preprints of the above papers, as well as others of our research group can be found on the Supernetworks Center site.

Collaborations across continents during wartime help to reduce brain drain and also deepen the research insights. Very grateful for the collaborations with scholars in Ukraine, which continue. Giving enhanced visibility to scholars in Ukraine provides valuable professional and psychological support during very challenging times.

Many thanks  for the news coverage!

Thanks to ALL Who Took Part in Our International Conference on Dynamics of Disasters in Greece

It has been an incredibly busy, yet energizing, several few weeks with two international conferences on different continents and different seasons (summer and winter).

I'd like to take the opportunity to thank all those who took part in the 6th International Conference on Dynamics of Disasters, which took place in Piraeus, Greece, July 3-6, 2023.

The below collage was constructed to capture a few of the highlights.

The venue of the conference was the Historical Library of the Aikaterini Laskaridis Foundation in Piraeus.

We had the pleasure of hearing from outstanding plenary speakers, both practitioners and academics.

It was inspiring to see conferees representing many different countries including: Austria, Germany, Nepal, Japan, Canada, Greece,  Italy, Turkey, the UK, and the US.

In a period in history with compounding disasters, the exchange of knowledge and best practices and working together to address the great challenges that we are faced with are needed more than ever.

Information about the conference, including the presenters and their talk titles can be found on the conference website.

I had the pleasure of presenting work done with my PhD student at the Isenberg School of Management Dana Hassani and colleagues at the Kyiv School of Economics: Professor Oleg Nivievskyi and Dr. Pavlo Martyshev. The link to the slidedeck of the presentation can be accessed here.

Not everyone could join us because of visa and other extenuating circumstances. Sadly, in April, Professor Urmila Pyakurel of Nepal passed away. She was an avid participant in our previous Dynamics of Disasters conference. We paid a tribute to her in Piraeus. A PhD student of hers presented on their joint work. Urmila lost her life to cancer, which she had battled for many years. She was also a Humboldtian. You can read about some aspects of her amazing life here.

And, while I was at the IFORS conference in Santiago, Chile, July 10-14, 2023, at which I gave a keynote, we heard from Springer Nature that we are getting a contract to edit the volume: "Dynamics of Disasters: From Natural Phenomena to Human Activity." My fellow Co-Editors on this project are: Professors Ilias S. Kotsireas, Panos M. Pardalos, Stefan Pickl, and Chrys Vogiatzis. It was a pleasure to work with them on the organization of this very timely conference.
