About Me

I am a Ph.D. student in Computer Science at Rutgers University, advised by Prof. Zheng (Eddy) Z. Zhang.

My research lies at the intersection of quantum computing systems, and LLM reasoning. On the quantum computing side, I work on Hamiltonian simulation, fermionic simulation, quantum circuit compilation, and hardware-aware optimization. On the LLM reasoning, I am interested in improving the reasoning capabilities of large language models through inference-time steering, scalable oversight, and weak-to-strong learning.

Before joining Rutgers, I received my B.S. in Computer Science from Lanzhou University, where I worked with Prof. Yonggang Lu on graph machine learning and community detection. I also worked with Prof. Fajie Yuan at Westlake University on deep learning for biological applications.

Beyond Research

Outside research, I enjoy competitive MOBA games, singing, and community building. I also create content about Arena of Valor and other MOBA games.

I am the founder of the Lanzhou University Flyer organization, a student-led initiative that connects current students with alumni and shares information about graduate study, career development, and international opportunities.

I enjoy meeting people with different backgrounds and exploring new research ideas. Feel free to reach out if you would like to discuss quantum computing, large language models, AI for science, academic collaboration, or shared interests.
