=====Research=====
My primary research interest is the development of principled methods to ensure the quality of computer programs. 
I am particularly interested in //software model checking// and related techniques such as //computational learning//, //automata theory//, and //satisfiability modulo theories (SMT)//. I am also interested in the applications of applying these techniques to ensure the correctness of real-world programs (e.g., high-speed crypto code and MapReduce programs).
