个人简介

I am a full professor in the Department of Zoology, studying population genetics and evolutionary biology. I develop and analyse mathematical models to study how populations change over time. The aim of this work is to identify when and whether particular evolutionary transitions are possible. I am particularly interested in understanding the evolution of the following traits: - Ploidy level -- When are haploid or diploid life cycles favored by evolution? - Mating system -- How do mating preferences evolve? When is sexual reproduction favored over asexual reproduction? - The architecture of the genome -- How do recombination rates/mutation rates evolve? How do chromosomes evolve? I am also Director of the Centre for Biodiversity Research (please see http://www.biodiversity.ubc.ca).
