This theme emphasises quantitative approaches to understanding the pathogenesis and transmission of infectious diseases and involves epidemiology, genetics and evolution, and mathematical biology. It includes the epidemiology of endemic and exotic pathogens, mathematical modelling of host-pathogen interactions, and the informatics of pathogen evolution. Infectious disease epidemiology in Africa, India and the UK - Mark Bronsvoort Prof Bronsvoort leads the Epidemiology, Economics and Risk Assessment (EERA) group based at the Roslin Institute. Evolution and epidemiology of bacteria and viruses - Samantha Lycett Sam Lycett is Group Leader in Pathogen Phylodynamics based at the Roslin Institute, Infection and Immunity Division, developing computational methods to understand how viral and bacterial diseases spread through populations. Molecular evolution, phylogenetics and epidemiology - Andrew Rambaut Andrew Rambaut is a member of the Institute of Evolutionary Biology in the School of Biological Sciences, interested in the evolution of emerging human viral pathogens including Ebola, Zika and Influenza viruses. Respiratory viral epidemiology in children - Harish Nair Harish Nair is based in the Usher Institute of Population Health Sciences and Informatics. His main research interests lie in the epidemiology of childhood respiratory infections. Dynamics of infection in humans and animals - Mark Woolhouse Mark Woolhouse is professor of infectious disease epidemiology in the Usher Institute. His lab takes a quantitative approach to host-pathogen dynamics to inform disease control measures. Quantitative methodologies in the control of infections - Helen Stagg Dr. Helen Stagg is a Chancellor’s Fellow at the University of Edinburgh and Tuberculosis Lead for the Usher Institute of Population Health Sciences and Informatics.
