I am a demographer with broad interests in evolutionary ecology, infectious disease dynamics and public policy. I did my Phd at Imperial on the evolutionary demography of monocarpic perennials, then did post-doctoral research on the evolution of senescence at the Max Planck Institute of Demographic Research; on inference of tree demographic parameters at Duke University; and on infectious disease dynamics at Penn State and Princeton. From 2010 to 2014 I was a Royal Society University Research Fellow at Oxford University. I started at Princeton in February 2014.    


Questions that particularly interest me currently include: how will changing human demography change infectious disease incidence and spread? What drives dynamics of rubella through space and time, and what does this indicate for vaccine control? What are the key influences on dynamics of malaria inside the bloodstream of mice, and what does this imply for control as well as evolution of the parasite? When should reproduction occur in plants where reproduction is fatal (from an evolutionary perspective) and can we link this back to the genetic background using the model plant system, Arabidopsis thaliana
