I’m a Distinguished McKnight University Professor of Computer Science & Engineering at The University of Minnesota, where I am also co-leader of the GroupLens Research Lab. My research areas are human computer interaction, social computing, and recommender systems. I am active in my professional community, for example, having served as President of ACM’s Special Interest Group on Human-Computer Interaction and chaired the main conferences in my field. I also consult frequently on intellectual property litigation cases in my areas of expertise.
