I am a research scientist at Aptima, Inc in Woburn, Massachusetts, where I work on better ways for people to understand complex data.
I received my PhD from the Department of Cognitive Science at the University of California, San Diego. My advisor was Jim Hollan, who directs the Distributed Cognition and Human-Computer Interaction Laboratory alongside Ed Hutchins.
My research focuses on interactive information visualization. Specifically, I study visualization of time-based activity, including data such as video, sensor data, and annotations. My methods draw from those of cognitive psychology, cognitive ethnography, and computer science. As part of this research I have developed a number of software tools, including ChronoViz, a tool for visualization and analysis of time-coded multimodal data.
Prior to my time at UCSD, I worked for Charles River Analytics in Cambridge, Massachusetts, where I researched the human factors of multimodal displays.
