Broadly I am interested in evolutionary genetics, especially the evolution of sexual and mating systems, the effect of recombination on molecular evolution, and the evolution of sex chromosomes. Plants offer ideal study systems for pursuing these interests because of their remarkable diversity and comparative lability of sexual and mating systems.
I am studying the evolution of sex chromosomes in the plant genus Rumex (sorrels) using comparative genomic approaches. My research explores the evolutionary forces governing the formation of heteromorphic sex chromosomes, such as suppression of recombination and subsequent degeneration of the Y chromosome. I am also interested in the broader consequences of sex chromosome evolution, including their impact on sexual dimorphism, sex ratios and reproductive isolation.
