Research Interests

I have a broad interest in evolutionary biology and population genetics. My main areas of interest are the interaction of ecology and population genetics, the theory of speciation, and adaptation to (spatially and/or temporally) changing environments. Coming from a mathematical background, my work is mainly theoretical: I develop and analyze mathematical models of evolutionary processes. I have been working on a variety of topics including the evolution of genetic architecture under disruptive selection, the evolution of assortative mating in sympatry, the maintenance of polymorphism in migration-selection models, coalescent models with non-standard patterns of recombination, and stochastic models for the establishment of new mutations in temporarily or spatially changing environments.

Currently, together with Laurent Excoffier (University of Bern) and Mark Kirkpatrick (UT Austin), I am working on the consequences of range expansions on the establishment of neutral, beneficial, or deleterious mutations. We also plan to use approximate Bayesian computation to study the evolution of inversions in Drosophila melanogaster.
