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 to ensure properties of parallel programs. I am also working on an ongoing project called Gibbon that explores compiler optimizations that improve the performance of recursive tree traversals.
Previously, I worked on two research projects based around doing GPU programming in a functional style using embedded domain-specific languages. On the first, I contributed to Accelerate, aiming to extend the language and compiler to automatically divide work across multiple GPUs. On the second, I contributed to Obsidian, where I implemented an auto-tuning framework that used heuristic-based search to improve the performance of GPU kernels.
In the past, 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.
