Conservation Genetics Quantitative Genetics Species-level molecular systematics Plant genetic response to environmental stress/variation
Available upon request
Research Emphases My research primarily focuses on using genetic approaches to understand the evolutionary and ecological causes and consequences of rarity in endangered plant species. My research combines the fields of plant systematics, phylogeography, population genetics, ecological/quantitative genetics and genomics to understand evolutionary and ecological dynamics of rare plant species
My main research interests specifically focus on the four following areas:
Quantifying and understanding the relationship between geographic range size and levels of genetic diversity in lineages with rare and widespread plant species Understanding the potential for adaptive evolution, the genetic architecture of phenotypic traits, and how these are affected by environmental stress/variation in plant populations Using genetic data to help understand the ecology and reproductive biology of endangered plants to aid in applied conservation and restoration efforts Elucidating patterns of evolutionary history, phylogeography, and species boundaries in closely related species complexes containing endangered plant species
