Hi, I'm Ryan Lehmkuhl!

I'm a recent UC Berkeley EECS graduate interested in using cryptography to build decentralized and privacy-preserving systems.

I'm currently taking a gap year to work for Opaque Systems and will be joining the PDOS and CSS groups at MIT as a PhD candidate advised by Henry Corrigan-Gibbs in Fall 2022.

Outside of work, you will probably find me lost somewhere in nature, drinking excessive amounts of coffee, biking, or playing music! I also thoroughly enjoy studying various topics in philosophy, sociology, and psychology.
