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.

Innovative Spectroscopy Is Enhancing Protein Structure Determination

Proteins are central to many disciplines within the life sciences, not least protein-based pharmaceuticals. Changes in protein conformation, structure or interactions could have significant impact on efficacy and safety. Therefore, being able to understand what forms of a protein are present in their natural conditions, even if present only at low levels, is important for analysts.

Screening Strategies for Toxicants in Industrial Wastewater

With an increasing amount of industrial wastewater being discharged, methods to identify toxicants are urgently needed for source control and quality management. We spoke to authors of a recent article that examined the success of an extended suspect screening strategy to identify characteristic toxicants in the discharge of a chemical industrial park.
