After having developed statistical methods for the study of population dynamics in nature, my research focus has shifted since 15 years towards the study of three main topic :
* The study of dispersal evolution (causes, mechanisms and consequences). The approaches which have been developed are demographic, physiological, behavioural and genetic. Three model systems have been chosen to study the genetic and plastic responses of dispersal to variations in the environment, two lizards species, the common lizard (Lacerta vivipara, coll M. Massot) and the side blotched lizard (Uta stansburiana.coll B. Sinervo), and a ciliate (Tetrahymena thermophila).
* The study of trade offs and phenotypic plasticity. I have been interested by the link between predation/parasitism and clutch size or/other traits evolution. I alm also interested by the evolution, control and organisation of trade-offs, in particular with respect to phenotypic plasticity.
* Population structure and extinction rate. We examine the role of the different sources of heterogeneity (demographic environmental) and in particular internal (mating system, polymorphism, type of competition) in population viability.
