About Me

I am a Ph.D. student in Computer Science at University at Buffalo, State University of New York, fortunate to be supervised by Prof. Changyou Chen. Prior to this, I obtained my Master's degree from Zhejiang University and my Bachelor's degree from North China Electric Power University.

My research primarily focuses on Multi-modal Large Language Lodels (LLMs), including but not limited to vision-language and audio-language models. I have developed several parameter-efficient methods, such as cross-modal prompt tuning and training-free support sets, to facilitate and enhance the application of these pretrained LLMs in downstream tasks.

I am currently interested in leveraging Retrieval-Augmented Generation (RAG) and Knowledge Distillation (KD) to enhance the reasoning capabilities of multimodal LLMs. If you are also interested in related topics and would like to collaborate, feel free to drop me an email!
