About Me

Zihan Ding is third-year Ph.D. at Electrical and Computer Engineering Department, Princeton University, supervised by Chi Jin. He obtained a MSc Machine Learning specialist degree with Distinction from Imperial College London in Fall 2019. He previously worked with Dr. Edward Johns at Imperial Robot Learning Lab for his thesis project. Before Msc, he received two Bachelor degrees from University of Science and Technology of China in 2018, major in Photoelectric Information Science and Engineering (Physics Dept., Bachelor of Science) and dual in Computer Science and Technology (CS Dept., Bachelor of Engineering). His bachelor thesis is supervised by Dr. Jinming Cui and Prof. Yunfeng Huang. He has worked as research intern at Meta AI (FAIR, New York), Inspir.ai (Beijing), Tencent Robotics X (Shenzhen) and Borealis AI (Toronto).
Research interests: The ultimate goal is Artificial General Intelligence with long-term planning capability, potentially with Consciousness. It breaks down to sequential decision making problems and expressive models with generalization. Consequently my interests predominantly revolve around Reinforcement Learning with function approximations (deep RL) in single-agent or multi-agent scenarios (with game-theoretical insights), expressive gerative models and Large Language Models, and learning-based methods for robotics with generalization capability.


"Research is about intellectual pilgrimage when climbing the mountain of persent knowledge, self-talking, acquiring deep and structral understanding, capturing the flash of inspiration, quick prototyping, persuing rigorism, simplicity and beauty."
