I am a Professor in the Department of Computer Science and Vice-President Research & Innovation at the University of British Columbia. I was also a co-founder of Tasktop Technologies Incorporated.

My research interests are in software engineering with a particular interest in improving the productivity of knowledge workers, including software developers. My group develops tools to aid with the evolution of large software systems and performs empirical studies to better understand how developers work and how software is developed.

My teaching spans from introductory computer science courses to undergraduate and graduate courses in software engineering.
