Jake Januzelli
Cryptographer @ Columbia University

I am a computer scientist working on the foundations of cryptography and the security of practical cryptographic protocols. My current interests are in the aspects of post-quantum cryptography not motivated by Shor's algorithm; e.g quantum rewinding and the quantum random oracle model.

Currently I am a second-year PhD student at Columbia University, where I am advised by James Bartusek. I am a member of the CS Theory group and Crypto Lab, and I co-organize the Theory Student Seminar. I completed my masters in computer science at Oregon State University, co-advised by Jiayu Xu and Mike Rosulek. Before that I worked as a software engineer at Epic (this one, not that one) and completed my undergraduate degree in mathematics at Cornell University.

My other interests include movies, Brazilian jiu-jitsu, and science fiction.
