Biography

Bryan Grenfell is a population biologist whose work focuses on the interface between theoretical models and empirical data. His lab investigates the population dynamics of infectious diseases, with an emphasis on the epidemiological and evolutionary dynamics of control and vaccination strategies. Grenfell is particularly interested in understanding the nonlinear spatio-temporal dynamics of acute immunizing infections and how these are affected by control strategies. His research initially concentrated on measles and has expanded to include a comparative analysis of various pathogens, including influenza, rotavirus, RSV, Norovirus, HIV, HCV, and veterinary morbilliviruses. The lab also delves into phylodynamics, specifically how pathogen phylogenies are influenced by host immunity and transmission bottlenecks. Recent projects have included work on the dynamics of measles in developing countries and the implications of vaccine refusal, along with exploring the dynamics of influenza across human, equine, and avian populations. Current efforts are directed at understanding the population dynamics and control of rotavirus and synthesizing findings on immunizing infections with economic dynamics of vaccination.
