Meet our team

The Institute is strategically run and managed by a Senior Leadership Team (SLT) which comprises of three Directors that are overseen by the Institute Director and CEO Prof Bryan Charleston. Together the SLT provides expertise and knowledge to ensure the organisation evolves and continues to operate at the forefront of scientific research, vaccinology and diagnostics and surveillance to control and contain viral diseases of livestock and those that spread from farm animals to people.

Prof Bryan Charleston MRCVS, Institute Director

Dr Bryan CharlestonProf Charleston obtained a BVetMed from the Royal Veterinary College, University of London, UK in 1982. After a period of time in Large Animal Practice, studied for a Masters degree in Molecular Biology at University College London in 1988, then a PhD degree, as a Wellcome Trust Scholar, from the University of London, UK, in 1991. He then carried out postdoctoral research, as a Wellcome Trust Post-doctoral fellow, at the Royal Veterinary College and the Babraham Institute, Cambridge for three years.

He joined The Pirbright Institute (formally known as the Institute for Animal Health) in 1994 and focused on studies of the immune response to viral infections in cattle. In addition, he has provided advice on studies of the immune response to viral infections in cattle. In addition, he has provided advice and expertise on the design of infectious disease challenge models for a wide range of pathogens in important agricultural species.  His research group’s efforts are focused on understanding the immune response to foot-and–mouth disease virus in cattle to develop novel vaccines.

Dr Michael Johnson BSc(Hons) MBA PhD, Director of Capability

Dr Simon Carpenter, Head of Institute Core Capability Grant (CCG)

Simon CarpenterSimon Carpenter is an entomologist whose main research focus is the biology and ecology of biting midges within the genus Culicoides. He has worked on this group of insects for 18 years, beginning with his PhD which examined the Scottish biting midge in Argyll, Scotland.

Following these studies, he moved to The Pirbright Institute in 2002 to work within Dr Philip Mellor’s internationally renowned group researching the role of these tiny flies in arbovirus transmission. Simon became the Entomology group leader in 2011 and has since led a wide variety of externally funded projects on Culicoides and the viruses they transmit. In addition, Simon is science lead for the Biotechnology and Biological Sciences Research Council Core Capability Grant at The Pirbright Institute, a major public investment which funds infrastructure contributing to the Institute’s unique capabilities in virology and production of resources for research throughout the world.

Simon’s scientific studies have led to the publication of over 90 peer-reviewed papers and this expertise has also led to his involvement as an expert in responses to arbovirus incursions in the UK and beyond. He is a founder member of the OIE (World Animal Health) working group on Culicoides and an advisor within UK Defra expert groups on bluetongue and Schmallenberg viruses.

Ana Corral, Head of Quality Management

Ana Corral profile pictureAfter completing her degree and specialising in genetics and microbiology, Ana moved to the UK, from Northern Spain, and started her career as a Forensic Trainer. Subsequently, Ana worked in the private sector setting up new labs (e.g. genotyping testing), implementing new management systems (for example ISO/IEC 17025 for scrapie testing or GLP for Veterinary Residues Testing) and managing improvement projects. She has over 15 years’ experience of working in technical and quality management. 

Ana has been at Pirbright since 2015 managing the Quality and Environment team. She is also responsible for the organisation audit programme and the implementation of new laboratory software solutions. In addition, she is the Quality Manager for European Virus Archive goes Global (EVAg) and coordinates quality aspects of twinning projects between Pirbright and other organisations.

Ana works very closely with all departments across Pirbright, science and non-science, promoting a continuous improvement ethos and facilitating change. She, and her team, provides support to the organisation in all aspects of their work.

Prof John Hammond, Head of Programme: Enhanced Host Responses for Disease Control

John HammondJohn Hammond obtained his PhD in comparative immunology from the University of St Andrews before moving to Stanford University in 2003 to study the NK (natural killer immune cells) receptor evolution in mammals. In 2009 he moved to The Pirbright Institute with a Biotechnology and Biological Sciences Research Council (BBSRC) Institute fellowship to study NK cells in ruminants.

He now leads the Immunogenetics Group at the Institute studying the mechanisms and consequences of genetic variation on the mammalian immune system. The current focus is on the biology and evolution of immune cell receptors such as major histocompatibility (MHC) class I, NK cell receptors and immunoglobulins (antibodies) in livestock. As in humans all these molecules are highly diverse, but there are significant differences in how this diversity is generated and functions in ruminants.
The goal of this research is to determine the evolutionary history and functional significance of genetic diversity in current livestock breeds. This is underpinning the development of bespoke genotyping tools for the cattle breeding industry and leading to fine mapping the impact of variation on cellular immune function. As a consequence, differential immune responses during pathogen challenge can be traced back to genomic variation. A deeper understanding of this unique immune variation has the potential to improve disease resistance and vaccine efficacy in these key food producing animals.
