Chen Wang

I am currently a Fernbach Postdoctoral Fellow at the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory. I completed my Ph.D. in Computer Science at the University of Illinois Urbana-Champaign, under the guidance of Prof. Marc Snir.

My research interests include high-performance computing, storage system, system for AI/LLM, parallel file system, perfomrance analysis, etc. During my Ph.D. and postdoctoral research, I have extensively studied performance issues related to POSIX consistency and explored the design of next-generation high-performance storage systems. Many of the projects I have been involved in are centered around these areas.

Hiring

I will be joining Nanyang Technological University (NTU) in Fall 2025 as an Assistant Professor in the College of Computing and Data Science (CCDS). I currently have two fully funded Ph.D. scholarships available for the January and August 2026 intakes. If you’re interested, please check out this page for more details.
