Nicolas Stier

Co-Director of Core Data Science

I’m a Co-Director of Facebook Core Data Science (with Lada Adamic). Our work leverages innovative research to drive impact to the products, infrastructure and processes at Facebook, the company. We draw inspiration from a rich and diverse set of disciplines including Operations, Statistics, Economics, Mechanism Design, Machine Learning, Experimentation, Algorithms, and Computational Social Science (in no particular order). Between 2014 and 2017, I supported the Economics, Algorithms and Optimization team, which is one the areas of focus of Core Data Science.

Prior to coming to Facebook, I was an Associate Professor at the Decision, Risk and Operations Division of Columbia Business School and at 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.
