Greetings! I joined IBM Research in June, 2010 after receiving my Ph.D. in Computer Science from the Computer Science Department at Carnegie Mellon University.

My research interests broadly lie in human-computer interaction, although I strongly believe that the most interesting problems require a highly interdisciplinary approach. To that end, I'm interested in topics such as computer-supported cooperative work (CSCW), social computing, visualization, computational linguistics, machine learning, statistics, computer networking, experimental psychology, and social science.

Currently, my work is in the following areas:

• Psycholinguistic analysis and personality modeling
• User interfaces and visualizations for statistical anomaly detection
• Expertise modeling and interfaces that motivate users to improve their expertise
• Creative uses of technology to improve in-store retail experiences

In my former life, my research focused on collaborative online video. For more information about that work, please visit my site at CMU.
