I'm a first-year PhD Student at Columbia University, immensely fortunate to be advised by Carl Vondrick. I also collaborate with the wonderful Andrew Owens.

My research lies primarily in computer vision & multimodal machine learning, while drawing close inspiration from cognitive science. I would like to scientifically study intelligence and its emergence.

Toddlers and other ecological organisms - new to their sensory bubble [umwelt] - acquire intelligence partially through evolution and self-play with the physical world. Instead of heavily relying on human supervision, I study such self-supervised machines that capitalize on unlabeled, multimodal sensory data (sight, sound, touch, smell!) and their natural synchronization.

Previously, I graduated from Columbia Engineering with a B.S. in Computer Science, where I was introduced to research by Shuran Song and teaching by Paul Blaer.

Teaching/Service

I spent the majority of my undergraduate years learning to help teach, with the great Paul Blaer as my teaching mentor here. I am nostalgic of each wonderful iteration.
