I am co-founder and Chief AI Officer at All Hands AI All Hands AI, building open source AI agents OpenHands Stargazers for developers.

Before I join All Hands AI, I was a PhD candidate in Computer Science at the University of Illinois Urbana-Champaign, advised by Prof. Heng Ji. I also work closely with Prof. Hao Peng.

I’m interested in developing AI agents that can interact with computer through code, assisting humans, and continuously self-improving based on environmental observations and human feedback.

I received my undergraduate degree at the University of Michigan in computer science and data science. Previously, I was an intern at Google Research (2023, multimodal LLM pre-training), Microsoft (2022, unit-test generation), Bytedance (2021, lightseq Stargazers ), and Tencent (2020, distributed deep learning).
