I am currently a 4^th-year Ph.D. student at School of Computer Science and Engineering, Nanyang Technological University, supervised by Prof. Eng Siong Chng. Prior to this, I received my B.Eng. degree from University of Science and Technology of China in 2020.

My research topics are:

• Large Language Models (LLMs): Generative Seq2seq Learning, Speech LLMs, Text-to-Speech Synthesis with RLHF;

• Speech Processing: Efficient Adaptation of Speech Foundation Models, Speech Recognition / Translation / Enhancement;

• Multimodal: Audio-Visual Representation Learning, Video-to-Audio Generation;
