In this episode, we are joined by Professor Sharon Peacock. Sharon has worked on pathogen genomics, antimicrobial resistance and a range of tropical diseases in the UK and Southeast Asia for the last 25 years, most recently launching the Covid-19 Genomics UK Consortium (COG-UK) to provide SARS-CoV2 genome sequencing to Public Health Agencies. We chat about the role of COG-UK in identifying variants of concern, its impact on UK public health policies and the future of pathogen genomics.
