Chen Wang


I am currently at CASC at LLNL, as the 2022 Fernbach Postdoctoral Fellow.

I completed my Ph.D in computer science at University of Illinois Urbana-Champaign, where I was advised by Prof. Marc Snir.

My research focuses on high performance computing. I am currently working on I/O consistency, parallel storage systems, and MPI and I/O tracing. Other projects I am involved in: slient error detection and proactive data container.

We are consistently looking for students who are interested in HPC, Parallel I/O, File systems, etc. Contact me if interested.
