Joey Hong

I am a PhD Student advised by Professor Anca Dragan and Professor Sergey Levine, where I work on offline reinforcement learning.

Prior to joining my PhD program, I was an AI Resident at Google Research, where I worked on multi-task bandits as well as program synthesis.

Before that, I was graduated from Caltech where I worked with Professor Yisong Yue.

Current Research

I'm currently interested in pushing the capabilities of offline reinforcement learning, specifically in applications that involve interacting with humans, through a mixture of theory and applied work.
