Biography
I am a research scientist at the Language And Science AI Lab, Alibaba DAMO Academy.
Prior to that, I was a visiting postdoc researcher at the University of Illinois at Urbana-Champaign and
was a visiting lecturer (Macao Fellow) at the University of Macau.
I received my Ph.D. degree from The Chinese University of Hong Kong in 2020, supervised by Prof. Irwin King .
My research focuses on improving the trustworthiness of LLMs.
The Language And Science AI Lab at Alibaba DAMO Academy is hiring research interns to work on hallucination, RAG, medical LLMs, or other relevant topics. If you are interested, feel free to drop me an email (kenchanhp at gmail dot com).
