Systems & Networking I am Co-Director of Facebook Core Data Science with Lada Adamic. We work on a combination of innovative research and product work in the areas of Statistics, Inference, Machine Learning, Experimentation, Computational Social Science, Economics, Mechanisms, Algorithms, and Operations (in no particular order).
Between 2014 and 2018, I supported the Business and Operations group, one of the groups within Core Data Science. This group focuses on (a) Game Theory (Marketplace modeling, Mechanism design, Ads and Auctions), (b) Optimization (Capacity Planning, Network Design), (c) Econometrics, and (d) Operations Management. We have ongoing collaborations with Ads, Infrastructure, Finance, Procurement, Growth, Marketing Science, among others.
Prior to coming to Facebook, I was an Associate Professor at the Decision, Risk and Operations Division of Columbia Business School and the Business School of Universidad Torcuato Di Tella. I received a Ph.D. degree from the Operations Research Center of the Massachusetts Institute of Technology.
