Zichao Hu
I'm a Ph.D. student in Computer Science at the University of Texas at Austin, advised by Professor Joydeep Biswas. I graduated from the University of Virginia with a B.Science in Computer Engineering in 2022.
My research focuses on leveraging imitation learning, reinforcement learning, LLMs, and diffusion models to empower autonomous robots to understand and carry out human instructions while navigating safely and in compliance with social norms within human environments.
I am also a part of the Learning Directed Operating System (LDOS) project, an NSF CISE Expedition in Computing.
