Research
Research Statement
I am interested in the design and implementation of programming languages. In particular, two questions motivate most of my research: "Can this program be made simpler to use?" and "Can this program be made more robust?"
I focus on new language abstractions, end-user programming, and new debugging techniques. In particular, I am excited about improving the user experience when programming with spreadsheets and with crowdsourcing. My work often blends traditional programming language techniques, like program analysis, with statistical techniques.
