My name is Christian Kroer. I am an Assistant Professor at the Industrial Engineering and Operations Research department at Columbia University. Prior to that I was a postdoc with the Economics and Computation team under Core Data Science at Facebook Research. I hold a Ph.D. in Computer Science from Carnegie Mellon University, where I was part of the Electronic Marketplaces Lab, advised by Professor Tuomas Sandholm. During my Ph.D. I interned at Microsoft Research New York City, where I worked with Sébastien Lahaie and Miro Dudík, and Facebook Core Data Science, where I worked with Nico Stier and Eric Sodomka. I have also been affiliated with Facebook's Core Data Science team as a consulting research scientist.
I am a winner of the 2016-2018 Facebook Fellowship in economics and computation. I was a runner-up in the 2017 INFORMS Computing Society Student Paper Competition.
Some of my code can be found on GitHub.
