I'm an Assistant Professor at en:Macalester College in St. Paul. I build systems that empower people to be better contributors to online communities. My research draws on techniques from data-mining, interface design, and social science to encourage members to contribute better content to their communities, and enable communities to identify high-quality contributions from members. Over the last few years, I have shifted my research focus to largely center on Wikipedia.
I received my Ph.D. under John Riedl at the University of Minnesota with GroupLens Research. Before that, I worked at an early startup that built movie recommenders for companies like Blockbuster Video and Comcast. I have also worked for Target Research, Google, IBM Research, and Thomson Reuters R & D.
When not teaching or researching, I play jazz saxophone with Snowblind, play squash, and spend time with my wife Katy, son Sidney, and daughter Stella.
