Christian Kroer

Assistant Professor

Columbia University

My name is Christian Kroer. I am an Assistant 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, where I was advised by Professor Tuomas Sandholm. During my Ph.D., I also worked extensively with Professor Fatma Kılınç-Karzan.
