After several years in general mixed practice Richard joined the Animal Health Trust, based near Newmarket, Suffolk, the headquarters of British racing, where he acquired a breadth of experience in the epidemiology, surveillance and control of a range of equine infectious diseases, including influenza, strangles and equine herpesvirus. He was the Director of Epidemiology and Disease Surveillance and Acting Director of Research at the Trust when it closed in July 2020. Richard and his immediate team have been retained by the UK Thoroughbred racing and breeding industry and they continue to provide global disease surveillance and advice on disease prevention strategies and management of outbreaks.
