I am a PhD student in Computer Sciences at the University of Wisconsin–Madison, advised
by Dr. Michael Swift in the SCAIL group.
I’m broadly interested in systems research, with a focus on OS-level resource management, profiling
and characterization, and applying learned methods to low-level policy decisions.
This site is a hub for both my professional and personal interests.
