Biography

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 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 robotics and model-based reinforcement learning, such as: (1) structured representation learning of state and action, (2) factored/structured world modeling and planning, etc.

I interned at Amazon Science with Kari Torkkola and Dhruv Madeka in 2021 summer and at Microsoft Research Asia with Qi Chen in my senior year. Before, I worked with Prof. Hao Su at UC San Diego.
