Research

My research focuses on adaptive evolution. I aim to understand how mechanisms underlying adaptation affect genetic and phenotypic diversity in natural populations, and population growth and persistence in changing environments. Questions I have investigated in previous projects include: 

• How does natural selection acting simultaneously on multiple loci affect surrounding neutral polymorphism?

• What's the effect of the phenotypic complexity of mutation (pleiotropy) and of selection on parallel evolution, and on speciation?

• How does phenotypic plasticity affect interactions between evolution and demography in changing environments?

My current work combines theoretical and empirical approaches towards a better understanding and prediction of the dynamics of contemporary evolution. These situations where evolution is followed in real-time include (i) long-term monitoring of natural populations, (ii) experimental evolution in the laboratory, and (iii) resurrection ecology (reanimation of dormant seeds or diapaused eggs from natural banks). These approaches offer a unique opportunity to test the ability of evolutionary biology to produce predictions that can be used in applied fields such as the management of resistances, or the conservation of biodiversity in the face of global change.
