Department: Pathobiology and Population Sciences
Guillaume is a veterinarian and epidemiologist. He is experienced in conducting research at the interface between epidemiology and other disciplines, including virology, anthropology, economics and archaeology. He is currently involved in projects focusing on avian influenza, foodborne pathogens, AMR, peste des petits ruminants, and the role of live animal trade networks in the spread of animal and zoonotic diseases.
Guillaume graduated with a degree in Veterinary Medicine from the Veterinary School of Alfort, France, in 2005. He obtained an MSc in Ecology from the University Pierre and Marie Curie Paris VI in 2006, and completed a Doctorate of Veterinary Medicine in 2007. He joined the RVC as a PhD student in October 2007.
Funded by the Bloomsbury consortium, his PhD was undertaken in collaboration with the London School of Hygiene and Tropical Medicine and the Imperial College. Guillaume was awarded his PhD in 2011 and subsequently commenced a research fellowship.
One of Guillaume’s key research interests is understanding the way in which livestock production systems shape the emergence, spread, and maintenance of animal and zoonotic diseases. Much of his research has focused on the role of live animal trading networks in the transmission of infectious diseases, especially avian influenza viruses. His past and current research activities have included mathematical modelling of disease transmission, network analysis, qualitative and quantitative risk assessment, multivariate analysis, and designing and conducting field surveys in domestic and wildlife populations in Africa, Asia and South America. His research has been increasingly inter-disciplinary, involving collaborative work and the development of integrative approaches at the interface between epidemiology and virology, anthropology, economics, behavioural economics, archaeology.
Guillaume is currently the research coordinator of the UKRI GCRF One Heath poultry Hub (https://www.onehealthpoultry.org/). This project aims to assess the impact of poultry production intensification on the transmission and evolutionary dynamics of avian influenza viruses, foodborne pathogens and antimicrobial resistance. It is taking place in Bangladesh, India, Sri Lanka and Viet Nam. He is also involved in projects on Peste des Petits Ruminants, African Swine Fever, swine influenza and Rift Valley Fever.

Guillaume has taught veterinary epidemiology, statistics, mathematical modelling, and risk assessment at both undergraduate and postgraduate levels, in the UK and abroad, including in Bangladesh, Belgium, Canada, China, France, Ireland, Korea, Mexico, Thailand and Viet Nam. He has designed and regularly delivered introductory and advanced training workshops in network analysis and modelling.
Guillaume is a member of the applied epidemiology working group of the OIE/FAO network of expertise on animal influenza (OFFLU). He has contributed to several projects led by the Food and Agricultural Organization of the United Nations (FAO), aiming to inform surveillance and control programs in Asia and Africa. He has also contributed to the development of FAO global guidelines for the surveillance, emergency risk assessment and risk management of avian influenza A (H7N9). Guillaume was a member of the expert committee for animal health for the French agency for food, environmental and occupational health and safety (ANSES).
Behavioural Adaptations in Live poultry trading and farming systems and Zoonose Control in Bangladesh
This PhD project is focussed on optimising PPR vaccination campaigns through developing mathematical models of PPRV transmission in different endemic settings, to inform the design of vaccine programmes which are tailored to local contexts.
