Research
I investigate the evolutionary relationships at different scales in the milkweed and dogbane family (Apocynaceae). At the species level, I am working to understand the diversification of milkweeds (Asclepias) in North America, where more than 120 species have evolved over the last 5-10 million years. At the family level, I am working to understand relationships among genera, tribes and subfamilies of Apocynaceae to provide a framwork for investigating the evolution of the biochemical pathway for pyrrolizidine alkaloid production. To address these questions, I use the sequences of hundereds of nuclear genes and whole chloroplast genome sequences to infer evolutionary relationships.
