Samuel Judson

I am a doctoral candidate in the Department of Computer Science at Yale University, advised by Ruzica Piskac. I work on finding new ways to use formal methods and applied cryptography to further principled governance of technology. In practice, my research focuses on privacy preserving formal methods, as well as on accountability for algorithmic decision making through the descriptive application of rigorous program analysis.

For my graduate research I received a National Defense Science and Engineering Graduate (NDSEG) Fellowship from the Office of Naval Research (ONR). Before that I received my undergraduate degree from Marlboro College, advised by Jim Mahoney and Matt Ollis, where my Plan of Concentration focused on cryptographic authentication.

I also write humor.
