Hi there! I'm a Staff Research Scientist at SenseTime Research, working with Dr. Lei Yang. My research focuses on multimodal foundation models with an emphasis on spatial intelligence. As a side project, I lead DLP3D, an open-source framework for building real-time autonomous 3D characters. I received my Ph.D. from MMLab@NTU, advised by Prof. Ziwei Liu and Prof. Chen Change Loy, where I spent wonderful years exploring virtual humans.
