Research Interest and Biography

Our group advances trustworthy, physics-grounded, and efficient machine learning for complex dynamical systems and AI for Science. Our work spans robust perception and control (adversarial defense, out-of-distribution generalization, interpretable decisions, learnable safety barriers), continuous-time modeling (ODE/FDE/SDE, PINNs, graph dynamics) for accurate long-horizon prediction, and scalable foundation models via quantization and ultra-efficient spiking/binary networks for edge deployment.

I am currently a Professor (Special Appointment) at the University of Science and Technology of China (USTC). Before that, I was a research fellow at Nanyang Technological Universty (NTU). I received the B.S. degree in Electronic Information Science and Technology from USTC in 2015, and the Ph.D. degree from NTU in 2020, supervised by Prof. Tay Wee Peng.
