Biography

I am Fengcheng Yu, currently an M.S. student in Computer Science at the University of Southern California (USC), where I began my graduate studies in August 2025. I work with Dr. Yue Wang in the Physical Superintelligence (PSI) Lab on world models and generative modeling, in collaboration with Toyota Research Institute (TRI).

Earlier at USC, I worked with Dr. Ramesh Govindan (Northrop Grumman Chair in Engineering, Professor of Computer Science at the University of Southern California), focusing on mobile systems, particularly real-time mobile sensing and low-latency data processing for in-vehicle perception systems.

Previously, I received my Bachelor of Engineering degree from Sun Yat-sen University in June 2025. From 2022 to 2023, I conducted research in the YCLab led by Dr. Calvin Yu-Chian Chen (陳語謙) (Director of AI for Science (AI4S) at Peking University). From 2024 to 2025, I continued my research training in Dr. Guang Tan (谭光)'s laboratory at Sun Yat-sen University.
