growth environment or mates, they vary in their gender and potential for inbreeding, and many species are polyploid having more than two copies of each chromosome and gene.  I study the consequences of these plant attributes for evolution using a combination of field and greenhouse studies, quantitative genetics, and molecular techniques. 
 
My current research focuses on the adaptive role of maternal effects, cross-generation influences of the environment and maternal genes. In addition, I am investigating how the multiple gene copies in polyploids affect the accumulation of reproductive isolation that leads to speciation as well as the consequences of inbreeding.  
 
My students and I incorporate studies of invasive species, altered habitats, and climate change into our research because these novel conditions permit insight into mechanisms of evolution.
