Our understanding of how ecological and evolutionary dynamics are played out in nature has been revolutionized by a seemingly trivial realization – all species have spatial population structures at some scale. Within a spatial framework I combine epidemiological, experimental, and molecular approaches to understand how eco-evolutionary feedback loops drive species interactions.

Much of my work is focused on understanding how diversity is maintained in host and parasite populations. Understanding this is one step closer to answering questions of how risks of virulence and pathogen occurrence evolve – important questions from both basic and applied points of view

Host-pathogen evolution

Evolutionary epidemiology

Trophic interactions
