About Me


I am currently pursuing my PhD in Combinatorics & Optimization at the University of Waterloo under the supervision of Prof. David Jao.
My research focuses on analyzing the security of post-quantum protocols built from isogenies and algebraic lattices, particularly digital signatures.
I also apply quantum algorithmic methods to solve classical problems in computational number theory.
