Research interests
    I study programming languages and computer security. Most recently, my work has focused on language-based enforcement of information-flow policies and understanding declassification. I am also interested in secure concurrent and distributed computing, functional programming languages, type theory, linear logic, theorem proving and mechanized metatheory.
