Fengrui Liu

Undergraduate Researcher in Computer Science
School of Computer Science and Technology, East China Normal University
Shanghai, China

I am an undergraduate student in Computer Science and Technology at East China Normal University. My research focuses on audio representation learning, domain adaptation, Sim2Real transfer, and LLM personalization and alignment.

I am particularly interested in building transferable, reliable, and personalized intelligent systems that remain useful under distribution shifts and diverse user needs.

I am actively seeking research collaborations and summer internship opportunities in 2027/2028.

My current work spans physics-inspired neural networks and multimodal domain adaptation at the Institute of Software, Chinese Academy of Sciences; personalized alignment for AI safety at the Shanghai Institute for Intelligent Education; and Sim2Real audio representation learning at Shanghai Jiao Tong University.
