Professor Stefan Wuertz teaches and performs research at the interface of microbiology and environmental engineering. His research focuses on the structure and function of microbial communities in engineered treatment systems. He specialises in biofilm systems in wastewater treatment, the use of molecular tools to describe microbial communities and biological processes, and developing methodology to detect low-level pathogens in the environment. His research team develops bioprocesses and investigates environmental solutions to create novel and multi-scale interactive engineering platforms for multiple purposes, such as the production of single cell protein from waste streams as a feed source and biological nutrient removal in used water treatment systems. As a prolific researcher and educator steeped in both environmental engineering and life sciences disciplines, he strongly believes in studying fundamental biological and physicochemical processes to develop new technology that is sustainable and market-ready in the long term.
