I am an Associate Professor in Informatics at the University of California, Irvine, where I run the Personal Informatics Everyday (PIE) Lab .
I study how personal tracking technology can acknowledge and account for the realities of everyday life. More people are tracking today than ever before, and as a result they bring more varied expertise and goals than many apps and devices are designed to accommodate. I examine how the design of tracking technology can be improved, often prototyping and evaluating new design ideas. I also maintain the personal informatics paper browser , a tagged list of publications on the topic.
Beyond the Department of Informatics, I am affiliated with the Department of Computer Science (by courtesy), the Connected Learning Lab , the Institute for Future Health , and the Accessibility Research Collective . My research is generously supported by the National Science Foundation, Snap Inc., and internal UCI programs.
I completed my Ph.D. in Computer Science & Engineering from the University of Washington and my B.S. in Computer Science from the University of Virginia.
When I'm not working, I try to spend time outside by hiking or running. I also collect turtle figurines, plushies, and pictures.
