My research focuses on the genetics of reproductive isolation in natural populations. I use two different model systems -- Mimulus and Drosophila – to address key evolutionary questions:
What is the genetic basis of reproductive isolation?
What are the evolutionary forces that promote speciation?
How does gene flow influence the evolution of reproductive isolation?
What are the dynamics of polyploid adaptation and speciation? |
