Guillaume is a veterinarian and epidemiologist. He is currently involved in projects focusing on avian influenza, peste des petits ruminants, joint economic and epidemiological modelling, 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 infectious diseases. 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.
Guillaume’s MSc focused on the distribution of intestinal nematodes in tortoise populations in Galapagos, Ecuador. For his PhD research, Guillaume investigated the role of live bird market systems in the spread and maintenance of avian influenza A (H5N1) virus in Viet Nam and Cambodia. He has contributed to several research projects led by the Food and Agricultural Organization of the United Nations (FAO), aiming to inform surveillance and control programs in Viet Nam and in Egypt. He also contributed to the development of FAO global guidelines for the surveillance, emergency risk assessment and risk management of avian influenza A (H7N9).
Guillaume is currently implementing a £1.7 million project funded by the ZELS initiative, with Dirk Pfeiffer as principal investigator. This project aims to explore the epidemiology of avian influenza viruses and behavioural adaptations of live poultry traders and farmers in Bangladesh.
His other current research activities include assessing the role of live animal trade in the emergence and re-emergence of animal and zoonotic diseases, estimating the level of transmission of peste des petits ruminants virus in Ethiopia, and developing joint economic-epidemiological models of disease transmission within livestock populations.
