I am a Ph.D. candidate in the College of Information Sciences and Technology at The Pennsylvania State University, where I am co-advised by Professor Suhang Wang and Professor Xiang Zhang. I was an Applied Scientist Intern at AWS AI in California. I received my Bachelor’s degree in Computer Science and Technology from Chongqing University. My recent research interests lie in multimodal learning, foundation models and graph learning.

I'm actively seeking internship opportunities for Summer 2027. I'd love to connect if you think there might be a fit with your team!
