L. Thomas van Binsbergen is a PhD student in Computer Science at Royal Holloway, University of London, and an MSc graduate of Utrecht University. His work revolves around the specificying and prototyping programming languages. Notable are the contributions he made to the Utrecht University Attribute Grammar Compiler (UUAGC), implementing algorithms for compile-time scheduling of attribute evaluation based on dependency analysis. In recent years, Thomas has been associated with the PLanCompS project and has developed Haskell tools for defining and executing FunCons: highly reusable and modular components used in the formal specification of programming languages' semantics.
