My lab explores algorithms and interfaces for intelligent information systems that optimally connect people with information, especially for educational goals. Examples include search engines that can deliver the right kind of personalized information at the right time, and intelligent tutoring systems that learn when and how to be most helpful in teaching a particular student. Building effective, reliable systems like these will require new theoretical, algorithmic, and methodological advances in multiple research areas, including machine learning, optimization, information retrieval, and human-computer interaction. My current research is centered on education, but I'm also interested in mobile and health-related applications.
My Ph.D. is from the School of Computer Science at Carnegie Mellon University, where my advisor was Jamie Callan.
I was a member of the Language Technologies Institute. My undergraduate degree (B.Math.) is from the University of Waterloo. Apparently, I'm not the only one who thinks that CMU and Waterloo are a great combination!
I currently work with the following graduate students:
Feb 2015: I'll be presenting some of my group's recent work on the text analytics of student course feedback at the Southeast Educational Data Symposium at Emory University in Atlanta in late February.
Dec 2014: Our Project DSCoVaR, developing technology supporting middle school literacy, has received an Amazon Web Services in Education Research award.
Oct 2014: Happy to be visiting with colleagues this month to give invited talks at CWI in Amsterdam, a workshop on computational learning of language models in Stockholm, and an ETS-sponsored vocabulary assessment workshop in Princeton, NJ.
