Research

I am an Assistant Professor (starting September 2020) in the Computer Science Department at Stanford University. Prior to starting at Stanford, I spent a year as a Research Scientist at Facebook in the FAIR SysML Research group. My research interests are in the area of computer architecture, with a focus on promoting correctness and security as first-order computer systems design metrics (akin to performance and power). A central theme of my work is leveraging formal methods techniques to design and verify hardware systems in order to ensure that they can provide correctness and security guarantees for the applications they intend to support.

My research has influenced the design of the RISC-V ISA memory consistency model both via my formal analysis of its draft specification and my subsequent participation in the RISC-V Memory Model Task Group. Additionally, my work produced a novel methodology and tool that synthesized two new variants of the now-famous Meltdown and Spectre attacks.

My research has been recognized with IEEE Top Picks distinctions. I was also awarded an NVIDIA Graduate Fellowship (2017-2018) and selected to attend the 2018 MIT Rising Stars in EECS Workshop. I completed my PhD in Computer Science at Princeton University and my BS in Computer Engineering at Purdue University.

Prospective students: I am currently looking for motivated graduate students, postdoctoral scholars, and undergraduate researchers. Once admitted to Stanford, if you are interested in working with me, please send me an email with your CV to start a conversation.
