Denis is working on the development of the microbial process for turning NRD and carbon source into microbial biomass. He is also working on the design and development of the pilot plant at Lamballe.
Denis studied for his PhD (1988) in France and Canada at INRA, UTC and IAF, working on the development of large scale production of fungus spores for the biological control of plant pests.
After two years at the Biotechnology Research Institute in Montreal, working on process development of animal cell cultures (continuous perfusion cultures for monoclonal antibody production), he returned to France in 1990. There, he worked on the development of processes and reactors for compost production applied to the mushroom industry (Solid state fermentation).
Since 1993 he has taught industrial microbiology to masters and engineering students and conducts research at the University of Western Brittany.
After a sabbatical in 2000 at Scripps Institute of Oceanography in San Diego, he started to work on the anthropic impacts on phytoplankton microorganisms (with a specific focus on pesticides), using both in situ microcosms and lab bioreactors tools.
Since 2016 he has worked on agricultural waste treatment by microbial processes.
