Research Interest

The goal of my research is to systematically derive and develop efficient algorithms from new and emerging domains on current and future architectures. The main focus of my research revolves around the derivation of efficient algorithms, analytical models for mapping software to and from hardware, and abstractions for software implementations. The eventual goal is to develop a theory of high performance that identifies key hardware and software factors affecting performance so as to automatically generate high performance implementations for current and future architectures.
