Heading to the University of Cincinnati This Fall

After an exhausting job search, I’m happy to announce that I will be heading to the University of Cincinnati this fall, after accepting a job as Assistant Professor in the Operations, Business Analytics, and Information Systems (OBAIS) Department of the Lindner College of Business.

UC has a great department, with strong researchers and incredible people. I look forward to contributing my research in energy operations management and behavioral operations to their research portfolio, as well as teaching classes in simulation, sports analytics, service operations, and other topics in operations management and business analytics. A new building for the business school is under construction, set to open in Fall 2019.

It’s been a busy 4+ months. My main interview conference (INFORMS) was in October this year, pushing up the job search cycle a bit. I had flyouts in November, December, and January, and chose between offers over the last couple weeks.

Here is a summary of my job search process:
-I applied to 76 schools. In retrospect, I should have been a bit more selective, but applying is free and relatively quick.
-I received 28 first-round interview invitations, one of which I did not accept due to it being too late in the process. 18 of the interviews were in-person and held at INFORMS. The rest were either by phone or Skype.
-From those 27 accepted interviews, I was invited to 8 campus fly-outs. 1 occurred in November, 3 were in December, and 4 were scheduled for January. I had to cancel the last fly-out, due to receiving attractive offers and the visit occurring too late.
-From those 7 campus visits, I received 3 job offers.
-Today, I accepted UC’s offer.

It was great to meet so many members of my field during the search process. And thanks so much to my family, friends, and co-workers who helped guide and advise me during the process.

Book Review – Lights Out

Lights Out: A Cyberattack, A Nation Unprepared, Surviving the Aftermath
by Ted Koppel, 2015

The first thing that interested me about the electric grid was the question of its resiliency and protecting it from attack. While my academic research has mostly focused on economic questions, the topic of resiliency is still interesting to me. Koppel’s book discusses the possibility of losing control of the electric grid due to a cyberattack and urban areas having to cope with a loss of power for weeks or months.

Generally speaking, the US seems unprepared for a cyberattack. Assuming the government was not protecting a classified plan, they did not have a plan to share with Koppel for how to deal with a prolonged grid outage. It is unlikely that the government will provide food, water, and basic supplies if an outage exceeds a few days. The alarming part is how unprepared for this outcome most city dwellers seem to be.

About half of the book discusses the disaster preparation plans of more prepared people. While this was, by itself, interesting, it was a little far from discussing the resiliency of the grid. I would have preferred this section to be shorter. Few, if any, of the preppers were focused on an extended grid outage.

It is interesting (ironic?) that we are more connected than ever due to the internet, but in the event of an electric outage, we will be less connected than ever. There needs to be operational plans in place for how to handle an extended outage, and these plans should be communicated BEFORE the outage, as there will be little ability to communicate them after the outage. Seems like a good outlet for operations management and risk management.

I listened to this book on tape.

MIT to offer economics+computer science degree. Good for all sorts of online marketplaces that match buyers and sellers.

Owners of the Tesla 60kWh version of its Model S and Model X actually have the same battery as the 75kWh vehicles but the battery has been purposely limited or “damaged” to provide only 60KWh of mileage. Is is really less expensive for Tesla to build more expensive batteries for all cars (including the lesser version) than to create and keep two inventories of car batteries? Probably.

Book Review – The New Product Bet (Pre-Release?)

The New Product Bet
by Nils Rudi and Serguei Netessine

This book is a multimedia approach to teaching how to choose order quantities for new, high margin products with long leadtimes. The book is supposed to accompany an app that has videos and other multimedia to reinforce the lessons. My review is only about the book part of the package. The writeup and accompanying illustrations of the newsvendor problem, along with suggested efforts to gather demand information and/or shorten leadtimes, were very good. It would be a great introduction to the topic for a new student or product manager. The length (about 140 pages with lots of illustrations, maybe the equivalent of 50 pages of normal text) was also short enough to be easily digested by its target audience.

I am not sure what stage this book is in. Serguei brought a bunch of unfinished versions to one of his presentations at INFORMS 2016 and left them for the audience. There are still some passages/charts unfinished in my version, and I did not have a password to try out the multimedia sections of the book. In googling, the book does not seem to be for sale yet, and the picture above is my own. I hope it gets published soon.
