Theoretical Evolutionary Ecology Lab

Welcome to the website of the Theoretical Evolutionary Ecology lab of the Department of Ecology and Evolution at the University of Lausanne.

Adaptation to heterogeneous resources
Evolution of sexual systems
Evolutionary ecology of sexual selection and sexual conflict
Evolutionary dynamics of traits with lasting ecological effects
Population genetics of structured populations

Our lab is broadly interested in the evolutionary origin and maintenance of trait diversity within populations. We develop and analyse mathematical models to generate general and testable predictions about the ecological conditions that favour differences between individuals and about the genetic basis of such differences.
