I am a Ph.D. candidate at the University of Kent, UK. I started here in 2013. Previously I worked at Associated Compiler Experts in Amsterdam. I was born in Soest, the Netherlands. I speak Dutch, English and Danish.

My main interest is in the area of program analysis and transformation. I research and develop compilers, tracers, debuggers, profilers and virtual machines.

The topic of my current research is making tracing and algorithmic debugging for lazy functional languages such as Haskell practical and easy to use for real-world programs. My goal is to help programmers to understand their code and locate bugs in a systematic manner.

Previously I worked on analysis and transformation of reducible and irreducible loops, interprocedural optimization of recursive functions and out-of-SSA translation.

I have experience developing in LLVM, the CoSy compiler framework, the Glasgow Haskell Compiler, and Haskell debugging aids Hat, Hood and Hoed. I am most at home with the programming languages Haskell, Erlang and C, but I have experience with other languages and am keen to pick up more.

At the University of Kent I teach logic, logic programming, functional programming, concurrent programming and using Unix, at Master's and undergraduate level.
