About Me
Currently, I am an AI Researcher at Huawei Noah's Ark Lab, working with Dr. Liu Yong. Previously, I was a research fellow affiliated with the ECE department of National University of Singapore, under the supervision of Prof. Haizhou Li and Prof. Xinchao Wang from September 2023 to October 2024. I collaborate closely with Prof. Luis Fernando D'Haro, Prof. João Sedoc, and Prof. Alexander I. Rudnicky. I was also an NUS-Robert Bosch (SEA) IPP student (2019 - 2022) and Dr. Thomas Friedrichs was my supervisor in Robert Bosch (SEA). My research interests include LLM Alignment, LLM Evaluation, and Dialogue Systems.
