Research Interests:

Research in the Perkins Lab applies mathematical, computational, and statistical approaches to answer basic and applied research questions about the ecology and epidemiology of infectious diseases. This work focuses primarily on mosquito-borne diseases of humans. These diseases pose a risk to billions of people, are the subject of intense development of new interventions, and are highly sensitive to numerous forms of global change. Accordingly, the goal of our research is to attain a predictive understanding of where and when these diseases occur, what the impact of interventions will be in curtailing their burden, and how the distribution of these diseases and their response to interventions will change over time as a result of changes in their underlying drivers. Through this research, we hope to elevate the rigor of the information on which decision makers act, both in terms of accuracy and quantification of uncertainty. We accomplish this through three interconnected themes of our research.

  • Incorporating transmission dynamics into infectious disease mapping: With relatively few exceptions, geographic mapping of infectious diseases relies on phenomenological descriptions of relationships between disease and its drivers and disregards a rich body of theory on transmission dynamics. The first theme of our research seeks to devise new approaches that leverage transmission dynamics theory to enhance the interpretability and utility of infectious disease mapping.
  • Model-guided assessment of interventions for infectious disease prevention: Mathematical modeling has a key role to play in designing and interpreting studies to assess intervention efficacy and to make projections of the impact of interventions when deployed at population scales. The second theme of our research seeks to advance these capabilities for prevention of mosquito-borne diseases.
  • Infectious disease dynamics in the context of global change: The dependence of vector-borne diseases on environmental conditions makes them highly sensitive to multiple forms of global change. The third theme of our research seeks to understand the interconnected nature of these dependencies.
