Microbial metabolism of atmospheric trace gases, nitrogen cycling in forested watershed, nitrogen cycling in contaminated soil or sediment.
My scientific work is concerned with the understanding ofthe role of microbial populations in the biogeochemistry of nitrogen and carbon(methane) in terrestrial and aquatic ecosystems at various spatial scales. More specifically, I am interested inthe multiple ecological interactions that may happen between:
1) themethane-oxidizing bacteria and the ammonium-oxidizing bacteria, and
2) thedenitrifying bacteria and the methane producing archae.
These relationships are important inrelation with the regulation of trace gas exchange between terrestrial andaquatic ecosystems and the atmosphere. They are also a major factor in the fate of nitrogen as a nutrient interrestrial and aquatic ecosystems. Finally they are imortant in thedegradation of organic matter from natural or anthropic sources in soil or sediment.
