Huaicheng LIAssistant Professor, Virginia Tech CS Office: 1149 Knowledge Works II Email: huaicheng@cs.vt.edu Curriculum Vitae: [pdf] |
I am an Assistant Professor in the Computer Science department at Virginia Tech (since Fall 2022). I got my CS Ph.D. degree in 2020 from University of Chicago, followed by a 2-year postdoc position at CMU Parallel Data Lab (PDL). I also did a few internships with Microsoft Research (3x) and NetApp.
My group focuses on fundamental Computer Systems research in the areas of Operating Systems, Storage Systems, Memory Systems, and Systems Architecture. We analyze/benchmark, hack, design, and build systems to explore better systems support for modern/emerging {compute,storage,memory} x {hardware,interfaces,applications} for improved {performance,resource efficiency,programmability}. Our research themes are:
Our research have won prestigious awards (here), generated real-world impact with production deployment in data centers and up-streaming to the official Linux kernel. We maintain FEMU, a storage research platform widely used in the research community. All of our research are open-sourced.
For most up-to-date information, please refer to Huaicheng's CV.
I have the honor to work with the following amazing students:
