I am interested in ecology and in evolutionary biology. I am dissecting the factors affecting the processes of speciation and diversification by using theoretical approaches. In particular, my research focuses on neotropical Heliconius and Ithomiini butterflies which are now well recognised as excellent model groups to tackle those questions.

Research interest

Warning colour patterns are a compelling example of a trait involved in both ecological adaptation and mate choice. Thus, shifts in warning colour patterns should promote reproductive isolation between subpopulations via pre- and post-zygotic barriers. Polymorphism in warning colour pattern can therefore have implications on evolutionary processes such as speciation or clade diversification, both because of its `magic trait' properties and its effect on populations' geographical distribution.

My PhD thesis is supervised by Mathieu Joron (CEFE, Montpellier) and Marianne Elias (ISYEB, Paris). I am constructing a theoretical framework to tackle the following questions: How do constraints on species range imposed by Müllerian mimicry affect the speciation process? How can male mate choice evolve and how does it affect progress toward speciation? How do mimetic interactions shape the phylogenetic tree resulting from the diversification of a clade.
