About Me

I am a Postdoctoral Scholar in the Sky Computing Lab at UC Berkeley EECS. I work under the guidance of Prof. Ion Stoica. Prior to this, I earned my Ph.D. in Computer Science from Rice University, where I was fortunate to work with Prof. Ang Chen.

My research is in the general area of computer systems including machine learning systems, networked systems, and their security challenges.

I am a recipient of Google Ph.D. Fellowship (2022) and a finalist for Meta Ph.D. Research Fellowship (2022).

I will be joining the CS Department at Rice University as a tenure-track Assistant Professor in Fall 2025.

I am seeking self-motivated interns in the directions of LLM systems, networked systems, and system security. If you're interested, please feel free to reach out via email ['jxing AT rice.edu'].
