I'm a full time senior researcher at CWI with a part time full professor position at TU Eindhoven. I own a share of SWAT.engineering BV and lead the open source community around the Rascal metaprogramming language. I love to read and write code that analyses and transforms other code. Old code is valuable code, but how to maintain it when its complexity grows beyond human measures? That is my overarching research question. Also I'm invested in supervising PhD candidates and master's thesis projects.

I'm research group leader of CWI Software Analysis and Transformation (a.k.a. SWAT)
