I design and build more usable software development tools by applying human-computer interaction methodologies to software engineering. In particular, my tools aim to increase developer productivity while also improving code quality. See my research statement for more details. Projects that I have worked on include:
Reviewing code. The process of code reviewing is utilized by most major tech companies; however, it is extremely time consuming. We designed CFar, an automated code reviewing system at Microsoft, to enhance the collaboration among developers during code reviews.
Navigating code. Developers spend an inordinate amount of time navigating code in an effort to understand and modify it. We designed the Patchworks code editor to make revisiting relevant code significantly more efficient.
Refactoring code. Although most code editors provide ample support for restructuring code, visual language environments do not. We designed Yestercode and CodeDeviant to aid developers in refactoring and testing their code.
Information Foraging Theory. We applied a theory of how people seek information to the domain of software development. To do so, we conducted a series of empirical studies of developers debugging Java code using desktop and mobile development environments.
