During COVID-19 pandemic, she was involved with setting up SARS-CoV-2 testing of convalescent plasma donors in England, and the related international REMAP-CAP trial. She also has wide interests in molecular epidemiology and next generation sequencing. She also chaired the WHO R&D Blueprint group on Picornaviruses and was recently appointed to the WHO European Region Commission for the Certification of Poliomyelitis Eradication. She also leads the Blood Safety research team within the NIHR funded Blood and Transplant Research Unit at the University of Oxford, and also support NHS Blood and Transplant in part-time basis. This research focuses on transfusion transmitted viral infections aiming to improve our understanding of current risks and preparedness for emerging pathogens.
