As of Fall 2024, I am on the faculty job market.
[CV, Research Statement]
I am a final year PhD student at University of California San Diego advised by Deian Stefan and Stefan Savage. My research focuses on solving hard security problems in real-world systems using lightweight, practical verification[1,2,3]. I also spend time working on hardware security[4,5,6], compiler security[7,8,9], and occasionally find bugs in airplanes[10].
I completed my undergraduate degree in Computer Engineering at University of Illinois Urbana-Champaign.
