Introduction
Introduction
I am currently a fifth year student at Carnegie Mellon University. My advisor is Gerard Cornuejols from Tepper School of Business. My main research interest is combinatorial optimization with topics in packing and covering, perfect matchings, and strongly connected orientations.
I got a bachelor's degree in Combinatorics and Optimization and Pure math at the University of Waterloo in 2021.
