    • Research

    Our lab does work on a diverse array of evolutionary topics. The organizing theme that ties these topics together are evolutionary and population genetics. Much, but not all of the work we do, focuses on plants. More recently, we have also adopted the nematode, C. elegans, as a model system for some of the questions that we are addressing. Here are some of the areas that we are interested in:

  • Evolution of reproductive systems in plants
  • Genome evolution
  • Conservation genetics
