Ryan Doenges

Picture of Ryan

I am a Distinguished Postdoctoral Fellow at Northeastern working with Amal Ahmed. Before this I was a PhD student with Nate Foster. I am interested in compiler verification and programming languages.

My last name sounds like “DEN-jis” when I say it out loud. My full name anagrams to “try heron agendas”.
