About

I am a postdoctoral researcher at McGill University in compressed sensing and machine learning with an interest in high-dimensional probability and optimization. I'm currently supervised by Drs. Tim Hoheisel (McGill) and Simone Brugiapaglia (Concordia). I completed my Ph.D. Applied Mathematics in 2021 at the University of British Columbia, advised by Drs. Yaniv Plan and Özgür Yılmaz. I completed my M.Sc. Applied Mathematics in 2014 at the University of Toronto, supervised by Dr. Adrian Nachman. Before that, I completed a B.Sc. Math & Stats at McMaster University.
