Our research group is primarily interested the evolutionary biology and ecology of hosts, vectors, and infectious pathogens. We strive to understand the proximate and ultimate drivers of infectious disease transmission across various ecological scales, from dynamics within host individuals, to those that manifest within and between ecological communities across heterogeneous landscapes. A central theme of our work is to combine field, laboratory, mathematical, and statistical techniques to answer questions on the complexity of infectious disease transmission that could not be achieved through one technique alone. By elucidating these mechanisms that modulate infectious disease dynamics, we aim to inform strategies that limit opportunities for infectious disease emergence and develop evidence-based approaches that mitigate transmission risks.
