Mathieu Sperandio is Professor at the National Institute for Applied Sciences of the University of Toulouse, leading a group dedicated to sustainable waste and wastewater management. After a PhD in Chemical Engineering (1998), he went for postdoctoral stay at the laboratory of AWMC in Queensland University (Australia). He obtained a lecturer position in 2001 and Professor position in 2009. He was an invited Professor in Montreal Polytechnique (Canada) in 2010. He has supervised more than 22 PhDs, authored more than 70 scientific publications, 3 books and 3 patents. He is a member of the management committee of IWA (International Water Association) task group on Nutrient Removal and Recovery. His group works on process engineering strategies toward waste conversion into valuable products in the environmental field. He develops new bioreactor systems and optimization tools for exploring and exploiting the natural potential of diverse microbial resources in carbon and nutrient cycles.
