Hi, I am a final year undergraduate student majoring in Information and Computational Science in the College of Science at Northeastern University, and I am currently interning under the supervision of Prof. Lichao Sun in the LAIR(Lehigh AI Research) lab at Lehigh University. I also have in-depth cooperation with Prof. Xiang Li at Massachusetts General Hospital and Harvard Medical School. My research interests include Large models and their applications in biomedical scenarios. My long-term research goal is to make different large models a trusted, efficient and powerful tool in biomedical domain. I have published some papers with total .

I am seeking potential research collaborations and the position of industry research intern. If you are interested, please contact me.
