About Me

I am a Computer Science and Engineering Ph.D. student at the University of Washington, where I work with James Fogarty. I am broadly interested in Human-Computer Interaction and User Interface Software and Technology. I am especially interested in designing, building, and studying systems that make software more flexible and extensible. I have also worked on dual-display mobile devices, crossing-based interfaces, and data analysis tools. I am an active member of the DUB Group, and in 2011 I was honored as a Microsoft Research Ph.D. Fellow.

Most of my work centers around Prefab, a system for reverse engineering interfaces from their pixels. Prefab enables the modification of applications independent of their source code. In other words, it lets us explore the question, "What if anyone could modify any interface?".

Here's a video of our latest work. We present a general-purpose implementation of a target-aware pointing technique, functional across an entire desktop and independent of application implementations. Specifically, we implement the Bubble Cursor, the fastest general pointing facilitation technique in the literature. Our implementation obtains the necessary knowledge of interface targets using a combination of pixel-level analysis and social annotation.

Here's a video of our work from CHI 2011. Prefab can be used to reverse engineer interface hierarchy (like a DOM for a web page) and content (like text).

Here's a video of our original Prefab work.
