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.
I am looking for PhD students, or possibly postdoc candidates – contact me or see here for more details.
