Bio

I am a research scientist at Meta. I received my Ph.D degree at the University of Illinois at Urbana-Champaign. I work closely with Professor Tianyin Xu and Professor Dan Williams from Virginia Tech. I received my bachelor degree in Computer Science from UCSD prior to grad school. My research interest falls in the area of Operating Systems. Specifically, my research focuses on constructing safe and expressive kernel extensions (e.g. eBPF and more) and their applications.
