My research activities focus on host-parasite interactions in the context of emerging zoonoses and changing environments (i.e. human disturbance, biological invasions). I lead an integrative research using both correlative and experimental approaches that combine concepts and methods from community ecology, parasitology, immunoecology, molecular biology and biostatistics. I conduct my research on different parasites/pathogen communities (bacteria, viruses, protozoa, helminths) circulating in small mammal populations (especially rodents) from natural and anthropized environments. I completed my PhD thesis in December 2015 (Universities of Montpellier, France and Dakar, Senegal) on the relationships between parasite communities, host immunity and invasion success of the black rat and the domestic mouse. I have performed my first post-doctoral (IRD-CBGP Montpellier, France) research on the spatio-temporal dynamics of wild rodents and their parasite communities (helminths and zoonotic bacteria) in an environmental change context. I am currently also interested in tackling the ecological and socio-economic issues associated with biological invasions at global and local scales using additional tools such as data mining, meta-analysis and modelling approaches. In my current post-doctoral research (Paris-Saclay University-ESE, Orsay, France), I conduct meta-analyses and develop predictive approaches on the worldwide impact of invasive alien species.
