Research interests

 My main research interests are in the evolutionary ecology of host-parasite interactions, focusing on the diversity of parasite''s strategies of host exploitation and the consequences on host population biology. The main topics of my studies are about:

  •  Manipulation of host sex ratio. I''m interested in vertically-transmitted parasites (Wolbachia (my former favorite parasite!) , microsporidia) as reproductive parasites of their crustacean hosts, their consequences on host reproductive strategies.

  •  Manipulation of host behaviour. The model organisms are acanthocephalan parasites, infecting freshwater crustacean intermediate hosts. I''m interested in investigating the causes for the variability observed in the manipulation (genetics, environment).

  •  Conflicts between manipulative parasites. How do parasites with different transmission strategies coexist in a single host? Are there conflicts and how are they expressed? What are the consequences for the host? I try to address these questions by studying the above-cited parasites.

  •  The role of biological invasions in evolutionary ecology of host-parasite relationships. The model organisms are the invasive amphipods and their parasites.

  •  More recently, I also began projects on sea urchins and their symbionts:  (1)  to understand the role of ectosymbiosis on benthic biodiversity in Antarctica; (2)  to understand how the life cycle of ectosymbiotic crab is shared between two hosts.
