My research generally involves parallelism and functional programming.
I am interested in designing programming languages to help programmers make better use of parallel hardware. More generally, I want to make software more efficient, especially through parallelism.
Currently, my research is about using types and functional programming abstractions to make parallel programming safer and easier. I am also working on an ongoing project called Gibbon that explores compiler optimizations that improve the performance of recursive tree traversals.
Previously, I did research on doing GPU programming in a functional style using embedded domain-specific languages in Haskell.
Even earlier than that, I briefly did research in artificial intelligence. I worked with Dr. Scott Gordon on a variation of the minimax algorithm designed to take more risks and set traps, and I developed a genetic programming library that is used in an undergraduate AI course.
