Sijun Tan (谭嗣俊)

I am a third-year CS PhD student at UC Berkeley, advised by Raluca Ada Popa. I am affiliated to Berkeley’s Sky Computing Lab.
Previously, I graduated from University of Virginia with a Bachelor’s degree in Computer Science and Mathematics, where I was advised by David Wu and Yuan Tian. I also worked with Professors Haifeng Xu and Xiaohui Bei. I interned at Facebook AI Research (FAIR) and worked at Ant Group as a senior algorithm engineer.
My work spans machine learning, computer security, and applied cryptography. Currently, my research focuses on enhancing the capabilities and robustness of Generalist AI Agents.
I am looking for highly motivated undergrads to work with! If you are interested in research opportunities, please send me an email.
