My main research interest is to understand the demography and adaptive evolution of both the pathogen and the host in a context of host switches / emerging pathogens. During the last years, I mainly focused on Plasmodium falciparum, the most virulent agent of human malaria but I am now also analyzing other kinds of zoonotic pathogens (viruses, bacteria). Working on emerging diseases lead me to study all aspects that lead a pathogen to jump from one host to another (diversity and characteristics of the pathogens in the donor species, in general wild animals; contacts between donor and recipient hosts), transmission of the pathogen from one host to another (including transmission ensured by a vector) and finally the genetic adaptation of the parasite to the new host as well as the response of the recipient host to the new parasite.
