James Choncholas

Ph.D. Student - Advised by Ada Gavrilovska
at Georgia Institute of Technology


Hi! I’m a computer science PhD student at Georgia Tech. My current research is in systems, solving optimization problems with garbled circuits in the context of localization (a problem in robotics) and in the context of machine learning. More generally, I’m interested in privacy preserving computation, cryptography, and secure systems.
