Hi there! I am Zhiwei Jia (pronounced Juh-Way Jee-A). You can also call me Sean. I am an Applied Researcher at Zoom, working on image & video generation models. I obtained my Ph.D. at UC San Diego, focusing on Embodied AI (i.e., multimodal AI agent). I was working with Prof. Hao Su and Prof. Zhuowen Tu.
