Arthur

Azevedo de Amorim

I am a postdoctoral researcher at CMU working with Anupam Datta and Matt Fredrikson. I am interested in programming languages, formal verification, and computer security.

I am from Campinas, SP, Brazil. I pursued my Ph.D. studies at the University of Pennsylvania, under the supervision of Benjamin Pierce and co-advised by Cătălin Hrițcu. Prior to that, I was a student at Unicamp and at Polytechnique. I am one of the authors of Software Foundations, an introductory textbook to the Coq proof assistant. I also have a blog about Coq.
