I am an assistant professor in the Programming Languages Group at Delft University of Technology.
I do research on specifying and implementing programming languages. I am particularly interested in type safe languages, i.e., languages with type checkers that verifiably guarantee the absence of errors in programs. My research focuses on principles, techniques, and tools that enable language designers to effectively define and verify type safe languages, and to maintain language definitions as a language evolves.
July 2019: I have been awarded a Veni grant on Composable and Safe-by-Construction Programming Language Definitions!
Mar 2019: I will be PC co-chair for the 2020 edition of PEPM (Workshop on Partial Evaluation and Program Manipulation). Submit your best papers!
