My research uses mathematical models and statistical analyses to address questions which arise in many areas of biology. My main interest is in the study of infectious diseases, including the epidemiology of childhood diseases (such as measles) and mosquito-borne infections (such as dengue).

More widely, I am interested in biological oscillations, such as circadian and ultradian rhythms, and the properties of biological networks (in a variety of contexts, including metabolic networks, epidemiological or social networks and neuronal networks).
