Research interests

The main objective of Professor Comte research program is to identify the response mechanisms of microbial communities to environmental disturbances and assess the impacts on the structure, functioning, and services of aquatic ecosystems.

  • Microbial ecology
  • Microbial diversity and function
  • Ecosystem functioning
  • Microbial biogeography
  • Physiology of unicellular organisms
  • Climate change
  • Northern aquatic ecosystems

Ph.D. Biology, Université du Québec à Montréal (UQAM)


Short biography
Before coming to INRS, Dr. Comte has worked as a scientist at the Canada Centre for Inland Waters of Environment and Climate change Canada in Ontario. Previously he had completed two postdoctoral training, one at the Department of Ecology and Genetics – Limnology at Uppsala University in Sweden and the other with Takuvik joint Université Laval (Quebec)/CNRS (France) Laboratory.
