Stefan Wuertz
Research Director (Environmental Engineering)
Singapore Centre on Environmental Life Sciences Engineering

Professor Stefan Wuertz teaches and performs research at the interface of microbiology and environmental engineering. He is Research Director for Environmental Engineering at the Singapore Centre for Environmental Life Sciences Engineering (SCELSE). He graduated from the National University of Ireland with a BSc degree in Microbiology, and subsequently received his PhD degree from the University of Massachusetts in 1992. In 2001, he completed his Habilitation in Environmental Biotechnology at the Technical University of Munich and joined the Department of Civil and Environmental Engineering, University of California, Davis. In 2007, he was awarded a Marie Curie Experienced Researcher Fellowship to return to Ireland on a sabbatical leave. He has been at NTU since 2011 where he co-founded SCELSE, and in 2019 became its Deputy Director, Education and Training. In 2016 he joined NTU full time as Professor of Environmental Engineering in the School of Civil and Environmental Engineering.

Research Statement

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.

 

Research One-liner

Professor Stefan Wuertz teaches and performs research at the interface of microbiology and environmental engineering to turn waste into useful products and ensure that water is safe to drink and enjoy.

We explored the relevance of bacterial biofilms in all habitats on our planet in a quantitative way.

We used ecological theory to understand how microbial communities evolve when under stress.

We laid the foundation for a quantitative approach towards detection of viruses in the environment by molecular means combined with large volume filtration.
