I am pleased to share an article by an aspiring medical writer from Poland. Hanna KurlandaWitek finished her PhD in geoscience at the University of Edinburgh, specialising in microbiology. After working in an environmental consultancy for a few years, she became a freelance science writer, writing about a variety of topics, from radioactivity, to viruses, to plastics. She has now started a career in medical writing, contributing here with an insightful article on biofilms aimed at creating awareness on the infections they may cause. Hope you enjoy this reading.
