Career Summary

I have worked as a clinical veterinary surgeon with a broad range of domestic and wild animals, and have experience of investigating and managing disease in a number of critically endangered and flagship species.

My current Wellcome Trust funded project is on zoonotic pathogen ecology in wildlife. This has introduced me to the fields of mathematical modelling and theoretical biology in infectious disease dynamics. My research since 2007 has focused on African fruit bats and their infections. My studies demonstrated a high prevalence (37%) of antibodies in one species of fruit bat (Eidolon helvum) against Lagos Bat Virus (LBV) (a genotype 2 Lyssavirus) and an as yet unidentified henipavirus (39%). Furthermore, we have identified a bat as seropositive against Ebolavirus in an urban environment.

Lyssaviruses typically have bats as their reservoir hosts; however rabies now has terrestrial carnivores as its reservoir hosts, following spillover infection from a bat reservoir. LBV has been isolated from terrestrial mammals and current rabies vaccines do not offer protection. Prior to the latter publication, henipaviruses were thought to be absent from the African mainland. The risk of spillover infection of these viruses is currently unknown, however Eidolon helvum is the most common fruit bat in Africa and lives in huge colonies, often in large African cities, and is a source of bush meat in West and Central Africa, providing opportunities for infection spillover to humans.

As well as working at CIDC and IoZ, I work in Professor Tony Fooks’ rabies and wildlife zoonoses lab, a WHO international reference centre for rabies at the Veterinary Laboratories Agency (VLA) Weybridge, and have conducted all laboratory work in BSL3/SAPO 4 facilities there. I have recently also joined Dr. Colleen Webb’s lab as a post-doctoral researcher at Colorado State University to learn further analytical skills and develop a model in order to understand the key factors that lead to the maintenance of LBV within the E. helvum colony.
