Gordon Stewart

I'm an Assistant Professor in the School of Electrical Engineering and Computer Science at Ohio University.

I do research in programming languages, interactive theorem proving, and software security. I received my PhD in Computer Science from Princeton in 2015 (adviser: Andrew Appel), and an AB from Harvard in 2006. Much of my research software is open source on Github. My picture is here. My CV is here.
