Research interests
I am interested in the mechanisms of host-parasite interaction, how hosts modulate concurrent infections, how infecting agents adapt their traits to optimize fitness and long term persistence at host population level and how host heterogeneities affect these interactions. Some of the questions I am addressing are: How is the dynamics of an infecting agent altered by a second infecting species? How does immunity affect shedding of infecting particles? Do close related hosts exhibit similar susceptibility to infections?
I am also interested in understanding how environmental conditions affect risk of infection. Questions I am addressing are: How do climate changes affect dynamics of parasite free living stages? How do habitat and host spatial structure influence the force of infection?
My current work focuses on:
- Immuno-epidemiology of host-parasite interactions
- Concurrent infections
- Host heterogeneities and consequences for parasite dynamics
- Climate change and risk of infection
