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 resource recovery systems. These models are then validated in laboratory-scale and full-scale experiments using molecular (DNA-based and RNA-based) microbiology and genomic techniques.
