I am Linfeng Zhao (赵林风), a CS Ph.D. student at Khoury College of Computer Sciences of Northeastern University since 2019. I’m advised by Prof. Lawson L.S. Wong and also working with Prof. Robin Walters. My research interests lie in the intersection of machine learning, robotics and artificial intelligence.

I study how structure helps improve learning and generalization in model-based reinforcement learning and planning and focus on robotic manipulation and navigation, including: (1) structured representation learning of state and action, (2) factored/structured world modeling and planning, etc.

During PhD, I interned at Amazon Science with Kari Torkkola and Dhruv Madeka in 2021 Summer. During undergraduate, I interned at Microsoft Research Asia during fourth year and earlier worked with Prof. Hao Su at UC San Diego.
