Isaac Potoczny-Jones

Research Lead, Computer Security

I have a fascination with both security and collaboration. As an open source developer, I thrive on openness and the “need-to-share” mindset, but some environments also have a “need-to-know” mandate. My mission here at Galois is to find innovative solutions for secure information sharing, and to see those solutions adopted.


In 2013, Isaac founded Tozny, a Galois spin-off company aimed at solving the password conundrum. With Tozny, the user’s phone is the key: Easier and more secure than passwords, Tozny replaces passwords with an easy-to-use cryptographic key on a user’s mobile phone.

Isaac is also a member of the Haskell open source community, where he was the first developer and maintainer of Cabal. He is also a member of the Debian community, where he was one of the implementors of APT’s secure package download framework. Isaac has been a professional Haskell developer for a while now; prior to coming to Galois, he worked at Ohio State University and Cisco Systems.

Isaac earned his master’s degree in Cybersecurity from the University of Maryland, University College, and his B.S. in Computer Science from Ohio State University.
