Hi there! I am a pre-doctoral researcher affiliated with the Prof. Wang's lab at UC San Diego and the Cognitive Tools Lab at Stanford University.

I received my Master's degree in Computer Science from UC San Diego, co-advised by Prof. Judith Fan and Prof. Xiaolong Wang. Previously, I obtained my Bachelor's degree from UC San Diego where I studied Computer Science, Mathematics, and Cognitive Science (minor).

Research

In early infancy, babies learn to track moving objects, gaze at unlikely events, and develop an understanding of object permanence and solidity. This process enables them to acquire knowledge about the categories, functions, motions, and intuitive physics of objects in the environment.

Given this observation, I pose a question: can artificial vision systems attain a comparable level of visual understanding and interpretation by observing the world through videos? This question naturally involves learning object properties from continuous visual observations with minimal supervision.

My research interests, therefore, reside at the intersection of self-supervised learning from videos, understanding structures of the physical world (e.g. object-centric representation), and human visual perception (e.g. visual abstraction).
