Chen Wang

I am an Assistant Professor in the College of Computing and Data Science (CCDS) at Nanyang Technological University (NTU). Before joining NTU, I was the Fernbach Postdoctoral Fellow at the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory, where I worked with Dr. Kathryn Mohror. I completed my Ph.D. in Computer Science at the University of Illinois Urbana-Champaign, under the guidance of Prof. Marc Snir. Fun fact: I have an Erdős number of 3 through Marc :).

My research interests include high-performance computing, storage system, system for AI/LLM, parallel file system, performance 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.

Teaching

NTU Undergrads: We’ve just restarted the Parallel Computing course (SC4050). Consider taking it if you’re interested in high-performance computing, supercomputers, or large-scale GPU programming. In addition, I am developing a dedicated GPU-oriented course (4000-level MPE), which I hope to offer starting in 2026.

Hiring

I am actively looking for self-motivated students. If you’re interested in working with me, please check out this page for more details.
