Hi! I co-founded and run TAISI, where I work on getting the Toronto–Waterloo corridor to transition to AI safety. I’m currently running an AI safety bootcamp with Julian, and thinking hard about what September looks like for the upcoming school year.

I’m interested in how AI strategy can inform field-building, and am constantly on the lookout for impactful projects in this space. Please reach out!

In September 2025, I set up and ran 5 cohorts of intro fellowships for 30 people, before co-founding TAISI with Julian in the winter.

I’m currently studying statistics and economics at the University of Toronto, where I heavily deprioritize coursework to focus on impactful things.
