about

I am a Postdoc at Stanford University, and was a Ph.D. student at Stanford from 2017-2023. I'm on the 2023-2024 academic job market!

I am advised by Professors Ashish Goel and David Mazières. I'm broadly interested in how the organization of computer systems interacts with computational performance and economic incentives. Lately I've been interested in the design and implementation of digital currency infrastructure.

I did my undergraduate degree in Mathematics and Computer Science at the University of Chicago.
