The Blood Supply Chain in the Coronavirus Pandemic

Much has happened since my most recent blogpost on March 7, which celebrated the successful PhD defense of my student, Deniz Besik.

On March 11, 2020, WHO declared a pandemic due to the coronavirus, which causes the respiratory illness now known as COVID-19.

As an operations researcher, who does research on various network systems, including perishable product supply chains, with applications in healthcare - blood supply chains and pharma supply chains, I had already been following a multiplicity of disruptions as the coronavirus was spreading globally.

In addition to the supply chain disruptions, I have also experienced professional ones as have virtually all academics worldwide as well as students.

I am on sabbatical now and was honored and delighted to have been invited to give seminars and plenary talks in multiple countries (Canada, France, Italy, and the USA, with others still on the horizon). These have all been postponed/cancelled causing not only disappointment but many foregone experiences, networking opportunities, and adventures.

But safety and health first, and we must do anything and everything in our power to mitigate the pandemic, and to flatten the curve.

I strongly believe that researchers, if at all possible, and if they have an inclination to do so, should write articles for the popular press. I saw the looming crisis in blood supply chains, having been following events in China and Iran, as closely as possible, because of COVID-19. I collected our relevant articles on blood supply chains (a topic we have been researching for the last decade), and impacts of disruptions, and wrote an Op Ed for The Conversation: How coronavirus is upsetting the blood supply chain

The article has now been reprinted in numerous publications including: SALON, MarketWatch, NavyTimes, EconTimes, and many others. I have been contacted by individuals who wish to help out. I have reached out to medical professionals that I know at top medical facilities to see if plasma of those who have recovered from COVID-19 may be used as treatment, as has been tried in China, supposedly with some success, and is now being investigated at Johns Hopkins.

The research that we have done on the blood supply chain includes the modeling of the perishability of red blood cells; the investigation of a disruption due to a major disease outbreak, which would result in a decrease in eligible donors, as well as disruptions to capacities of testing and processing, that clearly can happen with personnel being quarantined and/or struck by the coronavirus now. Our papers have also explored competition for blood donors using game theory as well as the design of blood supply chains plus the modeling of multiple tiers and even the competition among blood service organizations. We have also worked on quantifying the potential synergy associated with the merging or teaming of blood service organizations as in the case of a disaster.

Also,  we wrote a book to unify some of the knowledge on perishable product supply chains.
It is important to note that respiratory viruses are not transmitted via blood and all those who have the facility and the capability should donate. Since my article in The Conversation was published, the situation has become even more dire with severe blood shortages being reported by the American Red Cross. Blood, unlike many other products, cannot be manufactured, but must be donated by willing donors. Blood service organizations need to make this process now as comfortable and as easy for donors, as possible, by expanding mobile unit coverage, for example.

An update since the above post was published. Thanks to INFORMS Analytics for publishing my updated article to The Conversation piece in the Coronavirus Chronicles.

And now, as we move further into the pandemic, the possibility of utilizing convalescent plasma in different ways in providing potential therapies, is generating optimism, while, at the same time, there is growing competition among different organizations, and even profit-making ones, for Covid-19 survivors' blood plasma.

Bravo to Deniz Besik on Her Successful PhD Defense

Yesterday, was a very special day. Deniz Besik, who is my 22nd PhD student, successfully defended her doctoral dissertation at the Isenberg School of Management. The title of her dissertation is: "Essays on Competitive Perishable Food Supply Chain Networks: From the Impacts of Tariffs and Quotas to Integration of Quality." I had the pleasure of chairing her dissertation committee, which consisted of Professors Ana Muriel and Hari Balasubramanian of the College of Engineering at UMass Amherst and Professor Priyank Arora of my department at the Isenberg School.

Although the defense took place at 3:30PM on a Friday afternoon, the room was packed with Deniz's friends and colleagues and guests who had come to support her. Some had traveled from Boston and NYC to come to support her. Dr. Pritha Dutta, who was my 21st PhD student, and is now a Professor at Pace University, came from NYC.
Deniz in 4 and a half years as a doctoral student published 6 co-authored papers, which is an incredible accomplishment. Below are images of first pages of some of the articles.

Deniz was recognized for her research with the 2019 Outstanding Doctoral Student Researcher Award from the Isenberg School and took part in the INFORMS, POMS, and DSI doctoral colloquia. And, we recently heard that she was elected into the Phi Kappa Phi Honor Society. The ceremony will take place in early April and the UMass Amherst graduation in early May (assuming such events will be able to proceed, given the coronavirus).

The audience had great questions, given the timeliness of the dissertation as well as the clarity with which Deniz presented the results in her dissertation. Below is a photo of now Dr. Deniz Besik with her committee members after her defense.
And we managed to take a photo of some of the folks in the audience who stayed until after 5PM to congratulate her.
She was presented with flowers and I also gave her a gift.
Then it was time for a celebratory dinner, which took place at Judie's in downtown Amherst.
Followed by a very special dessert with candle.
I might add that Deniz during her doctoral studies also taught classes and she even served as the President of the UMass Amherst INFORMS Student Chapter. She has accepted a tenure track Assistant Professorship at the Robins School of Business at the University of Richmond in beautiful Virginia. The rewards of being a faculty member are many, but one of the best is seeing a very deserving and hard-working student achieve her dreams. We all wish Dr. Deniz Besik much continuing professional and personal success as she begins a new chapter as an Assistant Professor!
