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 science writer, 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.
