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.

A Global Mass Spectrometry Coalition To Combat COVID-19

A global coalition involving over 500 scientists, known as the COVID-19 MS Coalition, was announced earlier this week. The coalition aims to share mass spectrometry data on COVID-19 for the purpose of novel biomarker discovery and understanding the infection more deeply at a molecular level. Technology Networks spoke with Perdita Barran to find out more.

Why Are COVID-19 Scientists So Interested in What We Flush Away? Could Wastewater Predict a Second Wave of SARS-CoV-2 Infections?

As some of the stricter COVID-19 lockdown restrictions are being eased, some have already experienced a second wave of cases. But might there be a way to predict new epicenters of infection and nip them in the bud before they are able to establish themselves and spread further? Some scientists think so, and the answer lies beneath our feet – wastewater.

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.
