Upcoming Events
- (Hopefully we will be able to hold a gathering again...)
Research Interests
- Diagrammatic modelling of program execution,
for reasoning intensional, extensional and relational properties such as:
- Trade-off between space efficiency and time efficiency
- Observational (contextual) equivalence
- Dataflow manipulation in conventional programming
- More technically: interplay between interaction
(information-flow) semantics and rewriting
- Graph-rewriting abstract machines for functional programs,
guided by Girard's Geometry of Interaction
