I am a Senior Applied Scientist at Amazon AGI Foundations. Before that I worked at AWS AI Labs where I was part of the team that launched Titan Image Generator. I received my PhD at University of Maryland, College Park in 2020, advised by Professor Rama Chellappa. I received my Master degree from Shanghai Jiao Tong University and Bachelor degree from Dalian University of Technology. I interned at Waymo, Adobe Research, Palo Alto Research Center, and Siemens Healthineers during my PhD.

I work on foundation models for generative AI including auto-regressive modeling for vision-language multi-modality learning and text-to-image/video generation.



[Nov. 2023] Titan Image Generator is launched in AWS re:Invent 2023! (Amazon Science Blog, Press coverage: TC, theverge, gizmodo, venturebeat)

[Feb. 2023] PlolyFormer is accepted by CVPR 2023.
