I competed my PhD in microbiology at the University of Canterbury, New Zealand in 2014. My research focused on the fate and behaviour of enteric viruses in groundwater. After finishing my studies, I was involved in various project that uses viral metagenomics approaches to identify viruses (both known and novel) in various ecosystems. Since 2015, I have been working at the Bangor University, on the Viraqua Project (www.viraqua.uk; 2015-2018) and at the Shellfish Centre (2019-onward).

My research focuses on the ecology and survival of viruses in the aquatic environment with a special interest in the fate of enteric viruses. Enteric viruses are responsible for the majority of gastroenteral illnesses globally putting an enormous burden on healthcare systems and the wider economy. These pathogens are often found in water reservoirs (recreational and drinking water sources, shellfish harvesting areas) and hence responsible for water- and foodborne outbreaks. I design and validate methods for the recovery of enteric viruses in the aquatic environment in order to quantify infectious viruses, understand viral ecology, describe novel and emerging strains and model viral transport in the environment.
