Christopher G Leung

Machine Learning Engineer

I am a Machine Learning Engineer in Meta's Recommender Systems AI team focusing on cutting edge research in graph algorithms for user understanding. Before joining Meta, I was previously at Pinterest where I’ve primarily worked with technologies like GraphSage (GCNN) and multi-headed ranking models. Prior to Pinterest, I worked at Okta to deploy machine learning models to detect and prevent user account-takeover and large-scale cyberattacks.

I graduated from the University of Waterloo with a Honors Bachelor of Computer Science and am a member of Georgia Tech's Design & Intelligence Lab to research the intersection of cognitive science and AI.
