My name is Christian Kroer. I am an Associate Professor of Industrial Engineering and Operations Research and a member of the Data Science Institute at Columbia University. My research interests are at the intersection of operations research, economics, and computation, with a focus on how optimization and AI methods enable large-scale economic solution concepts. Previously, I was a postdoc with the Economics and Computation team under Core Data Science at Facebook Research. I have a Ph.D. in Computer Science from Carnegie Mellon University.

In addition to my academic work, I have extensive experience applying my work in practice. I have spent about six years as a research scientist at Meta in their Central Applied Science team (formerly Core Data Science) both full-time (during an internship and postdoc) and part-time (as a consultant) working on applying market design ideas to their advertising auctions and other operational problems such as prioritization of user notifications and alloation of blood donation nudges to users. I have also consulted for EliseAI, an AI startup for property management and healthcare scheduling, on building machine learning and optimization models for demand prediction, pricing, and scheduling. Finally, through funding from the Office of Naval Research, I have built AI and game theory-driven logistics tools for the US Navy that are getting deployed as part of the VITL-BMA effort.
