Profile of Dr Kata Farkas

Dr Kata Farkas
Postdoctoral Research Officer
(44) 01248 383056
Environment Centre Wales Building, 2nd floor


My research focuses on water microbiology; I study the fate, behaviour and ecology of microbes and viruses in water environment. I am particularly interested in the development of molecular techniques for the accurate quantification of bacteria and viruses in the environment, investigating viral survival and infectivity. I recently started to explore novel viral strains might be harmful to humans and animals and to describe viral ecology in relation to other microbes found in water using metaviromics.

I am currently the lead research scientist on the Viraqua Project at the Bangor University, Wales. The project aims to describe the fate and behaviour of wastewater-derived enteric viruses in the water and improve current risk assessment (

I am currently working on a NERC funded project entitled ‘New approaches for the quantitative detection of human pathogenic viruses within the freshwater-marine continuum’. The project aims are:

1. Develop robust technologies for the reproducible enumeration of viruses in different environmental matrices.
2. Evaluate new high-throughput molecular technologies for the rapid detection and characterisation of multiple target viruses from environmental samples.
3. Develop new time-integrating samplers which can be deployed in situ to capture low frequency, high risk events that are currently missed by traditional spot sampling.
4. Evaluate the application of the new methodologies to identify key viral inputs and reservoirs within the freshwater-marine continuum.
5. Use advanced mathematical models to improve prediction of viral flow from diffuse and point source discharges into high risk receptor areas (bathing waters & shellfish harvesting areas).
6. Develop and apply new techniques to evaluate viral infectivity.
7. Provide clear technical guidance on new virus methods and the use of those methods for risk assessment and risk management of shellfish and bathing water pollution.
