Debora MacKenzie has been covering emerging diseases for more than thirty years as a science journalist for outlets including New Scientist magazine. She has been reporting on Covid-19 from the start, and she was among the first journalists to suggest that it could become a pandemic. From SARS to rabies and Ebola to AIDS, she's been on the frontline in reporting on how pandemics form, why they spread, and how to stop them throughout her career. In addition to infectious disease, she also specialises in reporting on the science of complexity and social organisation. Before becoming a journalist, she worked as a biomedical researcher.
