Teresa Gea is a full Professor at the Autonomous University of Barcelona. Her research combines applied research with a more exploratory facet, searching for new bioconversion processes for the development of the circular bioeconomy. Without abandoning composting and anaerobic digestion processes, her activity evolved into a new research line in solid-state fermentation, with the aim of obtaining a greater recovery of organic waste, beyond compost and biogas. She has studied the production of hydrolytic enzymes, biopesticides and biosurfactants using different microbiological approaches. She has published > 60 papers and her h-index is 26, with >2100 citations, and an average over 250 citations / year in the last 3 years. She has participated in 9 national projects, a European H2020 project, and in numerous contracts with companies and administrations. She has been teaching on Environmental Technology, Sustainability, Bioremediation, Waste Management, and Chemical Engineering for more than 20 years.
