Alexandre Montpetit, Ph.D.

Faculty Profiles

montpetitAssistant Scientific Director, McGill University
and Genome Quebec Innovation Centre

Dr. Montpetit completed his undergraduate degree at the Department of Biochemistry of the Université de Montréal (class of ’96). He received a Ph.D. in Biochemistry in 2002, from the same institution, for his work on the genetics of acute lymphoblastic leukemia under Dr. Daniel Sinnett (at Ste-Justine Hospital). From 2002 to 2005, he completed post-doctoral research under Dr. Tom Hudson at the Montreal Genome Centre (which became the McGill University and Genome Quebec Innovation Centre in 2003) where he leaded large-scale genomic projects, mostly association studies for various complex traits and the Canadian portion of the HapMap project. In 2006, he became the Centre’s genotyping lab director and also the assistant scientific director.
Description of research:

Use of high-throughput DNA technology (genotyping and sequencing) in the discovery of genetic determinants of rare and complex traits such as Type II diabetes, cancer or neurological diseases. Other interests involve the development of bio-informatic methods for the analysis of structural variants, methylation profile and other types of variation from high-density arrays.
