Hi, I'm Rain Lehmkuhl! (he/they)

I'm a second year PhD student in the PDOS and CSS groups at MIT working under the excellent guidance of Henry Corrigan-Gibbs in the areas of cryptography, computer security, and systems. I am supported by an MIT Sunlin and Priscilla Chou Fellowship and an NSF Graduate Research Fellowship.

Before beginning my PhD, I worked at Opaque, a startup that provides a platform for collaborative data analytics on private data.

Prior to that, I graduated with a BS in EECS from UC Berkeley under the superb advisement of Raluca Ada Popa, Alessandro Chiesa, and Pratyush Mishra.

Professionally I go by Ryan, but outside of work I prefer to go by Rain. I have a bunch of random hobbies, but recently most of my free time has been spent dancing (mainly house)–hit me up if you want to take a class, go out, or travel to a festival! I always love meeting new people, especially other queer folk, so don't hesitate to reach out for whatever reason.

My email address is ryanleh [at] mit [dot] edu.
