I am an evolutionary ecologist interested in host-parasite interactions and kin selection across a range of systems. Current work, in collaboration with Sara Magalhães, investigates how competition between different parasite species impacts virulence-transmission relationships, and interactions mediated via the host immune system, between Tetranychus urticae and T. evansi. A separate project, also with Sara and mites, has been looking at the consequences of hard versus soft selection for sex allocation, sexual conflict and virulence.
In my previous life, before mites, I did a number of projects investigating the consequences of stress for host and parasite life-history, epidemiology and evolution. During my Ph.D at the University of Edinburgh with Tom Little I investigated parasite mediated selection in a natural population of Daphnia during an epidemic of a bacterial parasite Pasteuria ramosa. My first post-doc, with Yannis Michalakis at the IRD in Montpellier, looked at the consequences of coinfection for host and parasite life-history traits using a mosquito-microsporidian system. A second post-doc, with Oliver Kaltz at the University of Montpellier, used microcosm experiments to investigate how environmental fluctuation between permissive and stressful temperatures impacted parasite epidemiology in a Paramecium-bacterial system, and host-parasite coevolution in a bacteria-phage system. A third post-doc with Isabelle Olivieri at the University of Montpellier investigated local mate competition in spider mites.
