Dr. Deshusses' broad research interests are related to to the design and optimization of sustainable processes for waste and recalcitrant pollutants treatment in air, water and solids, and novel sanitation technologies. A current focus is on novel reactors and sustainable processes for air, water and sewage treatment with resources recovery. Applications include supercritical water oxidation, treatment of odors and air toxics, biogas production, and novel sanitation technologies (see also my sanitation research). Research interests include bioenergy and waste to energy processes, biofilms, monitoring microorganisms in complex environments using biomolecular tools, indoor air quality, gas-phase sensors based on functionalized nanomaterials, advanced oxidation processes for waste treatment, mathematical modeling of environmental processes and entrepreneurship.
