Associate Professor, School of Information
Electrical Engineering and Computer Science
My work is at the intersection of data mining and human-computer interaction. My research is focused on both modeling and the construction of new systems that leverage those models. Current projects include mining large-scale social media systems (Twitter, Reddit), networks (e.g., academic citation graphs), text/networks (meme propagation, information extraction, news articles, political networks), and cross-cutting methods (link prediction, community detection). Work on systems building includes new visualization systems (automated visualization, interactive machine learning, etc.), ranking systems (social feeds), and data-driven end-user support (end-user and developers).
