Risk Factors for Pathogenic and Antimicrobial Resistant Escherichia coli in Drinking Water based on nationally representative Household-Level Survey.
Characterization of candidate hydrolytic enzymes involved in pollutant biodegradation in stream biofilms
Application of Wastewater-based Epidemiology to SARS-CoV-2 Detection
A general barcoding approach to monitor invasive populations
We combine computational, experimental and clinical approaches to develop a clearer view of microbiomes.
Inhalation of legionella bacteria – which thrive in warm water – can cause illness: in a new project, an Eawag-led multidisciplinary research team is investigating how the risks associated with these bacteria can best be managed.
Microbial interactions determine the production of nitrous oxide
In order to better understand natural processes and also to be able to better control the activities of microbial communities in technical systems such as wastewater treatment plants, we need to understand how microbial communities work.
Fate of antibiotic resistance during microbial range expansion
Exploration of the impact of water chlorination on fecal carriage of antimicrobial resistant bacteria amongst a cohort of Bangladeshi children
Differences between individual cells can be important for biological processes.
Virus Transfer at the Skin-Liquid Interface
Growth Kinetics and Gene Transfer of Enteric and Environmental E. coli in Domestic Settings
Microbial stability in reclaimed and treated grey water
Antimicrobial resistance has emerged as one of the major health threats of the 21st century.

Completed projects

Consequences of environmental fluctuations on the spatial self-organization of microbial assemblages
Biofilms on materials in contact with potable water can be manipulated due to their dependencies on material composition.
Unexpected changes in source water microbial quality can profoundly influence the efficacy of drinking water treatment resulting in potential risk to consumers.
Improvement of methods for testing the influences of polymeric materials on drinking water quality and preventative measures for commissioning of new domestic pipe systems.
Microbial communities provide important services to ecosystems and human society.
Even without genetic resistance bacteria can be tolerant to antibiotics.
Individual variation and cellular memory help bacteria deal with environmental fluctuations.
Even with effective drinking water treatment, microbial growth in the household is inevitable and can lead to problems for consumers
Individual microbial cells rarely exist alone in the natural environment. Instead, they typically arrange themselves in space relative to other cells.
Plastic materials are of major environmental concern.
Hexachlorocyclohexanes were extensively used during the last century as insecticides for the control of agricultural pests.
