I’m a fifth year PhD student at the University of Pennsylvania in the department of computer and information science, advised by Steve Zdancewic, and a part of PL Club. I do research in the field of programming languages. In the fall of 2020, I did an internship at Galois working with Eddy Westbrook.

I did my undergrad in computer science at the University of Waterloo, where I was in the co-op program. I did research with Ondřej Lhoták and Vijay Ganesh. I also did software engineering internships at Kongsberg Geospatial, The Coalition, Improbable, and Microsoft.

Algebra for Honours Mathematics - MATH 135 (Undergraduate Marker): Fall 2014

I wasn’t able to TA much during my undergrad. I did do some one on one tutoring for a variety of computer science and math courses during my last few years at Waterloo. My favourite to tutor (and most often tutored) was Algorithms (CS 341).
