Juridical AI

What makes legal judgment
worth trusting?

I’m developing Juridical AI into a startup, beginning with tools for legal education and professional supervision. The aim: make the reasoning, verification, and human decisions behind AI-assisted legal work visible.

Its research includes Project Rainmaker, a proposed study of how experienced lawyers review AI-assisted transactional work. The platform and studies are in development.

AI & investor
protection.

At Osgoode’s Investor Protection Clinic, I am a Research Fellow. My research examines how AI is reshaping investor protection—from investment advice and disclosure to AI-enabled fraud and market manipulation, and the potential for AI to improve retail investors’ access to redress and justice. I also contribute to the Clinic’s research, publications, policy work, and student training.
