About Me

I am a third-year PhD student at UT Austin, advised by Prof. Kristen Grauman and Prof. Alex Dimakis. My research lies in Machine Learning and Computer Vision, specifically in the following topics:

• Video as a Unified Representation of the World
• Multimodal models for Video Understanding/Reasoning
• 3D/4D Modeling from Videos
