General information

 Professor Frigon’s research interests encompass several aspects of environmental biotechnology with a focus on microbial community engineering. His research aims at constructing mathematical models describing the dynamics and activity of microbial populations present in wastewater treatment systems. These models are then validated in laboratory-scale and full-scale experiments using molecular (DNA-based and RNA-based) microbiology and genomic techniques.

Current and future research projects

  • Diurnal microbial population dynamics in municipal activated sludge systems
  • Description of heterotrophic niches in municipal activated sludge systems
  • Metabolic modeling of Rhodococcus RHA1
  • Metabolic modeling of enhanced biological phosphorus removal
