About me
About me
I am currently a research scientist at AMD GenAI. I received my PhD degree from Department of Computer and Information Science, University of Pennsylvania, advised by Professor Dan Roth. Before going to Penn, I was a master's student at University of Illinois, Urbana-Champaign.
My research generally focuses on retrieval/faithfulness of knowledge, long-context understanding, math reasoning, and LLM/VLM training.
