I work on algorithmic statistics and machine learning. My research is part of broader efforts in Foundations of Data Science, Machine Learning, and Theory of Computation at Columbia.

If you are a (current or prospective) student interested in coming to Columbia and/or working with me on research, or if you are generally interested in getting started in machine learning and/or research, please check this page of frequent answers to questions.

My papers can be found by following this link. (See also arXiv and Google Scholar.)


I’m lucky to be able to work with several outstanding students and postdocs.

I’ve also worked with other fantastic students on their thesis research, including: Mathias Lécuyer, Avner May, Cun Mu, Karl Stratos, José Manuel Zorrilla Matilla.
