Biography

I am a PhD student at The Hong Kong University of Science and Technology, supervised by Prof. Ying-Cong Chen and Prof. Qifeng Chen.

We are always looking for self-motivated undergrad/master/mphil students to for research projects in Video/Image Generation, LLM/MLLM Reasoning. Students from both campuses of HKUST are especially welcome (other universities are also welcome). Feel free to ping me via Email or WeChat if you are interested in working with me!
