I am a Ph.D. candidate studying with Robert Jacob in the Human-Computer Interaction Lab at Tufts University. My hope is that someday, our computers will know exactly how, when, and in what quantity we should interact with information to match our unique experiences, personalities, and working environments. My research at Tufts explores the use of passive brain-computer interfaces to optimize and personalize our engagement with information.
My work also looks at the use of visualization tools to support analytical tasks with Remco Chang at The Visual Analytics Lab at Tufts (VALT), and I have an ongoing project with Mira Dontcheva, Aaron Hertzmann, and Zhicheng Liu in the Creative Technologies Lab at Adobe. In the past, I have investigated leveraging the computing power and intelligence of casual gamers to help solve NP-complete problems with Charles Cusack.In addition to presentations at ACM CHI, IEEE InfoVis, and Augmented Human, my research has been featured in New Scientist, Discovery News, and ACM TechNews, as well as other magazines and blogs. You can read articles I've written about our work in IEEE Computer and ACM XRDS. You can also find me talking and thinking about technology on Twitter.
