I am a PhD-track MSc student in Computer Science at the University of British Columbia (UBC). I am supervised by Dr. Frank Wood at PLAI.
I work on World Action Models (WAMs), primarily DiT-based video and action policies, focusing on making joint generation more robust through compute-efficient methods (see WAM-Mini). I also have ongoing projects in test time adaptation, real-time anomaly detection, and browser-use agents, the last funded through MITACS by Layer6 (TD Bank).
I previously earned a Bachelor of Commerce from Concordia University, then spent two years in marketing at Sid Lee.
