Adrian Smith

University Lecturer in Infectious Diseases & Fellow of St Catherine’s College

Adrian Smith’s research focuses on understanding the basis of immunity to infection, including the study of immune mechanisms that operate in birds and mammals.

In particular, he is interested in how T lymphocytes contribute to immunity in the gut. The outcomes of this research contribute towards the development of effective immune interventions, such as vaccines. These could be especially valuable in protecting the food supply chain by reducing the impact of infection in livestock (e.g. control of coccidiosis) and preventing the transmission of diseases from livestock to humans including Salmonella, Campylobacter or avian influenza.

Dr Smith also works on the biology of pattern recognition receptors including the Toll-like Receptors which are important in the initial recognition of microbial challenge and the responses generated by adjuvants after vaccination.

Adrian Smith holds Jenner Investigator status in recognition of contributions to vaccine development (
