Broad research specialisms: Ecological interactions, Ecology of aquatic microbial communities, Experimental microbial ecology, System ecology, Antibiotic resistance in the environment and in the human gut. I work on interactions between microbes, primarily by studying bacterial coexistence in controlled environments (experimental microbial ecology).
Research interests: I like to use microbes as model organisms to test general ecological theories (community response to natural stressors, interactions prey-predators, competition and/or cooperation between species, resistance and resilience of microbial communities). I try to define trends and ecological models to apply the ecological theory to concrete problems associated with bacteria (mostly in waters, but also in soils and human gut) including microbial blooms, antibiotic resistance, and spread of pathogenic bacteria.
Research projects: Microbial coaggregation and cooperation; Impact of predation and competition on microbial model systems; Natural antibiotics resistance, and impact of AB on community resilience; Genotype-phenotype relation in aquatic bacteria; Ecological invasions of stressed systems; Limnology of large or remote lakes and of wastewaters.
