Research on efficient, reliable, and aligned foundation models.

I am a second-year M.S. in Machine Learning student (And incoming Ph.D. in ML) at Carnegie Mellon University advised by Prof. William W. Cohen. Before CMU, I completed my B.S. in Computer Science at the University of Rochester, where I was advised by Prof. Jiebo Luo.

My research focuses on efficient training and inference, model alignment, and evaluation for large language and vision-language models. I am currently a Student Researcher at Google Research advised by Dr. Si Si, and I also collaborate with Prof. Jiaxin Huang and Prof. Haohan Wang.
