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.

Why We Should Consider Our Food Packaging and Not Just Our Food

Whilst we can detect some contaminants by their taste or aroma, not all contaminants can be detected by our senses. Mineral oil-based chemicals are one such group and are attracting increasing interest from food analysts as we found out when we spoke to Professor Erich Leitner, a leading expert on food quality at the Graz University of Technology in Austria.
