I have particular interests in the epidemiological dynamics of various virus infections of humans and other animals, including influenza, African horse sickness, canine rabies and emergent lyssavirus and henipavirus infections and the methods needed to study them. Bovine tuberculosis poses interesting challenges at the interface of science and policy and is an important disease and challenge. Funded studies include the bovine tuberculosis control, emergence of zoonotic viruses, especially in Africa, transmission dynamics of mammalian influenza viruses and their variants through natural hosts and orbivirus dynamics. I co-supervise several students working on the dynamics of emergent viral infections in bats, in particular Eidolon helvum, in Ghana.
In addition to my research interests, I am also involved in the Cambridge-Africa programme, which focuses on building links between Cambridge and African Institutions and which aims to strengthen Africa's own capacity for a sustainable research (http://www.cambridge-africa.cam.ac.uk/).
