I currently work at the National Institute of Advanced Industrial Science and Technology (AIST) in Japan.
Hybrid system modeling: in embedded systems, it is often necessary to model the physical environment a program operates in, alongside the program itself. Many factors make it necessary in such models to mix continuous evolution, governed by differential equations, with discrete events (like state changes in the controller or collision). Consistently specifying the order in which such events happen, or what happens when an order cannot be discerned (think of three balls simultaneously colliding at one point) is challenging. I'm interested in the theory and implementation of programming languages that have well-defined semantics in those cases, and/or filter out such cases by type systems or other forms of static analysis.
Multi-stage programming is a general framwork for type-safe program generation and metaprogramming. I'm interested in its basic metatheory and type systems, and also in using it to write verifiable (or just less buggy), efficient programs.
