Simon received his PhD from the Liverpool School of Tropical Medicine, where he developed a cattle model for testing vaccines against onchocerciasis. After post-doctoral positions working on vaccine development for Theilerioses at the Centre for Tropical Veterinary Medicine, Edinburgh, and the International Livestock Research Institute, Kenya, Simon joined the Virology Department of the Animal and Plant Health Agency, Weybridge as a research fellow in immunology. In 2014, he took up the joint position of Group Leader (PRRS Immunology) at The Pirbright Institute and Senior Lecturer in Veterinary Immunology, within the new School of Veterinary Medicine at the University of Surrey. Simon’s research is focused on improving our understanding of the interactions of the PRRS virus with the porcine immune system and the development of improved vaccines.
