Research Description
In most pathogens, epidemiological and evolutionary processes occur on similar time scales due to the large population sizes and short generation times. This makes infectious diseases amenable to study and the interplay of their ecology and evolution particularly relevant for both fundamental biology and applied public health. However, temporal and spatial changes in infectious disease dynamics are difficult to anticipate due to the effects of environmental drivers on the transmission of pathogens and the complex diversity that these microorganisms exhibit.
To address these challenges, my research on the ecology and evolution of infectious diseases focuses on the following general questions:
- How do climatic and demographic factors shape the population dynamics of infectious diseases in space and time?
- How does pathogen diversity interact and interfere with public health interventions?
For answering these questions, I use mathematical and computational tools that are applied to different types of time series data.
