Ph.D. Student @ Stanford University

About Me

I am a Ph.D. student at Stanford University advised by Prof. Stefano Ermon. I previously received my bachelor’s degrees in Computer Science and Applied Mathematics at University of California, Los Angeles and was advised by Prof. Song-Chun Zhu and Prof. Ying-Nian Wu. My goal is to create human-centered embodied agents that can understand the world like humans do. Towards this end, I mainly research in computer vision and machine learning, and build models that understand the world in a structured and probablistic manner. I am broadly interested in generative modeling and representation learning, both in unimodal and multimodal settings.

I was a co-founder at Apparate Labs (acquired by Luma AI) focusing on real-time visual visual synthesis of human-centric videos.
