Biographical Information

I am currently a full professor at the University of Quebec at Montreal where I teach Computer Science. Prior to joining the University of Quebec, I was a researcher in the Internet Logic group at NRC and the group leader of the e-Health Research Group. Before joining NRC, I was a professor at Acadia University, an industry consultant, and a NSERC postdoctoral fellow at the Institut de génie biomédical. During my days in industry, I designed the Waaves format for the National Radiology Server (in France) and Signal Processing software for the geophysical industry — see the video on Google Video. I earned my Ph.D. from the École Polytechnique de Montréal and graduated from the University of Toronto.

Consulting Services

Since 1998, I have regularly worked as a consultant on projects having to do with my research expertise. I am mostly interested in projects having to do with very large data sets (terabytes). From 1999 to 2001, I ran my own consulting firm full time and worked with numerous clients. From 2003 to 2005, I was a research officer at the National Research Council of Canada where part of my job description included working with industrial clients.
