Members of the Waterborne Pathogens group
Tarja Pitkänen

I am the Waterborne Pathogens Group leader and Associate Professor (tenure track) in the field of Environmental Health at the University of Helsinki as a part of HOH Helsinki One Health Network. I have gained my expertise on detection methods and infection risk assessment of microbes in water during my work at the Water Microbiology Laboratory, Finnish Institute for Health and Welfare, where I co-affiliate as a Chief Specialist. I hold an adjunct professorship in molecular water microbiology at the University of Eastern Finland, where I gained my PhD on Environmental microbiology in 2010. My research interests involve molecular detection and the characterization of health-related microbes and zoonotic pathogens in water.

Annastiina Rytkönen

I am a PhD student in the Waterborne Pathogens Group working on topics related to microbial source tracking, microbial risks in watersheds and ruminant intestinal pathogens. I have background in biochemistry and I have gained experience on environmental microbiology research as well as molecular biology methods, qPCR and QMST while working at Water Microbiology Laboratory, Finnish Institute for Health and Welfare. My research interests include topics around the shared health of environment, humans and animals, such as  zoonotic and environmental pathogens, and the risks they cause in the changing environment. 

Ananda Tiwari

I am a postdoctoral researcher with a Ph.D. on water and health related microbiology. I conducted my doctoral studies on monitoring of microbial quality of bathing water, at Water Microbiology Laboratory of Expert Microbiology Unit at the Finnish Institute for Health and Welfare (Supervisor: Associate Professor Tarja Pitkänen). My research interest includes indicator bacteria (Escherichia coli and intestinal enterococci), microbial source tracking, virus indicators, beach monitoring, Vibrio cholerae, Cyanobacteria, microbial ecology, antibiotic-resistant bacteria/ genes, wastewater based epidemiology, drinking water distribution system, and biofilm production.
