About me

I am a Ph.D. student studying combinatorics and optimization at the University of Waterloo under the supervision of Dr. Ricardo Fukasawa. Previously I completed a M.Sc. in computer science at the University of British Columbia, under the supervision of Dr. Bruce Shepherd. On the side, I make open source software for digitally processing audio and generating algorithmic music and visuals under the alias byte.observer. When not in front of a computer or whiteboard I can usually be found rock climbing, foraging for mushrooms, cycling, snowboarding, hiking or cooking.

Competitive programming problems

After competing for many years I was given the opportunity (thanks Zac!) to create original problems for a programming contest. It turns out that I enjoy making problems even more than just solving them! Most of my problems are available on Open Kattis, where anyone can try them out.
