About me
I am a postdoc at IBM Research Almaden. Prior to that, I was a postdoc in the Stanford Theory Group. Even prior to that, I obtained my Ph.D. from the Computer Science department of Columbia University, where I was advised by Prof. Rocco Servedio. Long ago, in a distant land, I received a M.Sc. in Computer Science from the Parisian Master of Research in Computer Science, and an engineering degree from one of France's "Grand Schools," the Ecole Centrale Paris.
Here is a link to my résumé (updated 01/25/2020).Research Interests
My main areas of study are property testing (with a focus on distribution testing), learning theory, and, more generally, randomized algorithms and the theory of machine learning. Additionally, I am interested in online and approximation algorithms, as well as stochastic processes.
