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?" Surprisingly, the answers to these questions often complement each other.
My work focuses 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. I employ traditional programming language techniques like program analysis, but somewhat unusually, I often blend these with statistical approaches.
The exercise of building real software often reveals important flaws and shortcomings in one's research. I strongly support the practice of submitting software 'artifacts' to optional Artifact Evaluation Committees. Building these artifacts does indeed substantially increase the effort required to do research. But artifacts are worth the time because they enable reviewers (and others) to validate one's claims independently.
My work on CheckCell, ExceLint, and FlashRelate were all awarded "Artifact Verified" badges. FlashRelate was awarded PLDI '15's "best-of" prize, the Distinguished Artifact Award. I am in good company, as my colleagues in the PLASMA Lab won the PLDI Distinguished Artifact Award
