Research Scientist · Cantina
I am a Research Scientist at Cantina, where I work on generative foundation models. Before that, I was a Senior Research Scientist, focusing on generative AI, at the Intelligent Creation team at ByteDance / TikTok.
I received my master's degree from UC San Diego, where I was fortunate to work with Prof. Manmohan Chandraker at the Visual Computing Center.

Research
I currently work on video foundation models, with a focus on building generative models that understand and synthesize dynamic visual content, including world models, video generation, and editing. Over the past few years, I have worked extensively on personalized image and video generation, while also exploring efficient training and inference methods. Prior to this, my research focused on 3D vision and graphics, particularly in areas such as 3D reconstruction and neural relighting.
