Senior Research Scientist @ Salesforce Research Ph.D in Machine Learning @ NUS |
His current work focuses on multimodal agents and reasoning, also with applications in temporal analysis. He has experience in leading or co-leading multimodal generation projects, including MagicEdit and MagicAvatar for video generation/editing, PeRFlow for generation acceleration, and AdjointDPM for controllable generation. He was also involved in several large-scale multimodal projects, including Aria MLLM, MagicVideo, and Allegro. He will be dedicated to developing advanced AI for workflow automation and task planning.
He did PhD with Prof. Vincent Y. F. Tan and Dr. Jiashi Feng in NUS, with a research focus on robust deep vision models and optimizers. He also has been working closely with Dr. Junnan Li and Dr. Jun Hao Liew.
