Research Interests

Much of my research uses models to study the population and evolutionary dynamics of spatially structured populations. Current work focuses on (1) developing models of invasions that incorporate increased biological and environmental detail such as genetics and habitat variability  (2) understanding the dynamics of populations living at biogeographic range margins  (3) using models to make general predictions regarding the consequences of habitat destruction and climate change for biodiversity (4) the causes and consequences of mutation rate – including understanding how elevated mutation rates may lead to antibiotic or pesticide resistance (5) the evolutionary ecology of longevity.
