About

I am an assistant professor in the programming languages group at the department of software technology at Delft University of Technology. My research interests span many aspects of program verification, for example:

• Concurrent separation logic: I am one of the main developers of the Iris framework for concurrent separation logic in Coq, which has been deployed very effectively in a wide variety of verification projects. These projects include but are not limited to: verification of fine-grained concurrent data structures, logical-relations for relational reasoning, program logics for relaxed memory models, program logics for object capabilities, and a safety proof for a realistic subset of the Rust programming language. Take a look at the Iris website for the many exciting applications of Iris.
• Proof assistants: I am an active user of the Coq proof assistant; nearly all of my research has a corresponding mechanization in Coq. Moreover, I am the main developer of coq-std++: an extended standard library for Coq.
• Tactic languages: In order to carry out proofs at the right level of abstraction, I have worked on the development of various tactics languages for the Coq proof assistant. Notably, I am the designer of the MoSeL (formerly Iris Proof Mode) tactic language for separation logic proofs in Coq, and have contributed to Mtac2, a next-generation tactic language with support for strongly typed tactic programming.
• Semantics of real programming languages: In my PhD thesis, I have developed a semantics and separation logic for a large fragment of the C programming language. More recently, I have contributed to Rustbelt: the first formal (and machine-checked) safety proof for a language representing a realistic subset of Rust.
• Multilingual software: I have recently been awarded a prestigious Dutch NWO Veni grant (250.000 EUR) to work on the semantics and reasoning principles for interaction between different programming languages via shared-memory and asynchronous message passing.

Before becoming an assistant professor at TUDelft, I have received my PhD (cum laude) from Radboud University Nijmegen under the supervision of Freek Wiedijk and Herman Geuvers, and have been a postdoc in Lars Birkedal's group at Aarhus University.
