I graduated with a Ph.D. from the Institute for Communicating and Collaborative Systems in the Division of Informatics at the University of Edinburgh. My academic advisors were Bonnie Webber, Graeme Hirst, and Katja Markert. The topic of my dissertation was "Resolution of Other-Anaphora" (i.e., noun phrases with the modifiers "other" or another"). You can download my dissertation and other research papers here.
During September 2001 - August 2003, I was also a guest doctoral student in the Computational Linguistics Group in the Department of Computer Science, and a scholar-in-residence in the Interactive Media Lab in the Department of Mechanical and Industrial Engineering, both at the University of Toronto.
