Water treatment plants and analytical laboratories work hard to ensure that by the time drinking water reaches your tap it is safe to drink. Contaminants and the routes of contamination can be numerous and diverse, so it is imperative that suitable and sufficient testing is performed to identify any potential dangers.
After completing an undergraduate degree in Natural Sciences at the University of Cambridge in 2006, Karen became a research scientist at the Animal Health Trust, UK. During her time there, she completed a PhD in molecular microbiology and evolutionary genetics in partnership with the University of Cambridge and went on to hold a post-doctoral position. Her research focused on the fundamental biology of infectious diseases, outbreak analysis and the development of vaccines and diagnostic assays. In 2017 she left the lab to pursue a career in science communication. As senior scientific specialist, Karen employs her wealth of knowledge and hands-on experience to coordinate and create a range of scientific content, tools and resources for the site and provide scientific support across the teams.
