My main research topics are convex optimization, statistics and machine learning. I am deeply interested in understanding to what extent noise can influence regularization for optimization problems. My current Ph.D. supervisor is Carola Schönlieb, who is head of the Cambridge Image Analysis (CIA) group at the Department of Applied Mathematics and Theoretical Physics (DAMTP). I am still mostly working with my past supervisor Quentin Berthet who works in the Brain Team of Google Research.
