Robbert Krebbers



I am associate professor (universitair hoofddocent, ius promovendi) and vice department head of the department of Software Science of Institute for Computing and Information Sciences at Radboud University Nijmegen, The Netherlands.

My research is centered around scaling up program verification techniques to challenging programming paradigms like concurrency, higher-order functions and modules, and applying these techniques to programming languages like C, Rust, and Scala. I like to build solid mathematical foundations and usable tools, preferably using the Coq proof assistant.

The main research project I am currently involved in (and I am leading together with Ralf Jung) is Iris: a framework for concurrent separation logic in Coq. Iris has been deployed in a wide variety of verification projects, for many different programming languages, at many different institutes world-wide. Together with my Iris co-authors I received the 2023 Alonzo Church Award for Outstanding Contributions to Logic and Computation. Check out the Iris website for more information!

I have received my PhD (cum laude) from Radboud University Nijmegen (2011-2015), have been a postdoc in the logic and semantics group at Aarhus University (2015-2016), and an assistant professor in the programming languages group at Delft University of Technology (2016-2020).

Bachelor and master projects

I am always looking for motivated bachelor and master students. If you are interested in a thesis project related to program languages (in particular, in the field of concurrency, language semantics, separation logic, and Coq), do not hesitate to contact me.
