I am an evolutionary ecologist with background in both ecology and molecular biology, a taste for statistics, and a fascination for adaptive evolution, life history trade-offs, and animal behaviour. I take a particular joy in designing experiments grounded in theory. Beyond their value as model species I am generally curious about all animals.
I am currently exploring links between predation and extra-pair mating, drawing from models by Christian Joergensen and Sigrunn Eliassen on the evolution of female promiscuity and cooperation in socially monogamous species (Click here).
Using longitudinal data combined with field experiments, I am investigating extra-pair mating within neighbourhoods (click here for a nice Nature News & Views on the topic!).

I am also interested in life history evolution, with a particular focus on parasite life histories.
Because they have a very tight relationship with the hosts on which they rely, parasites often experience strong selection, and hence may display rapid adaptive changes in their life-history traits. I have been investigating how the conditions prevailing in salmon aquaculture may select for faster life histories and higher virulence in the salmon louse Lepeophtheirus salmonis (Click here).

I have also been studying how parasitic infection affects host behaviour in wild passerine birds.
In southern France and Corsica (CEFE CNRS lab in Montpellier, click here) female blue tits Cyanistes caeruleus garnish their nests with aromatic plants. Via field experiments I have shown that by doing so they reduce bacterial loads on their offspring, especially those most infested with ectoparasites, which in turn makes them grow faster. This behaviour thus appears as a special kind of maternal care taking the form of preventive medication.
In populations of great tits Parus major studied by researchers from the EGI in Oxford (Click here) I have studied how avian malaria affects the social behaviour of hosts, and how bacteria are spread on social networks.
