The work in my laboratory centers on reproductive barriers between higher plant species, in particular between species wild tomatoes. We are examining the molecular and cellular nature of interspecific reproductive barriers (IRB). Our investigations include genetics (including analysis of both natural variation and transgenic approaches), next generation sequencing, and pollen tube growth studies.
