Alexandre Bayle


I am a third-year PhD student in the Department of Statistics at Harvard University, where I am fortunate to be advised by Professor Lucas Janson. My research interests lie at the intersection of statistics, machine learning and probability.

Prior to Harvard, I received my M.S. (Ingénieur Polytechnicien Program) from the École Polytechnique with a specialization in Applied Mathematics and Computer Science.
