Research in our lab centers on plant systematics, phylogeny, evolution, and biodiversity, with an emphasis on plants in the Solanaceae (tomato family). We use a variety of approaches from morphology to molecular phylogenetics and a diversity of techniques from field and herbarium studies to DNA sequencing to delimit and describe species and investigate their evolutionary relationships, distributional ranges, and basic biology. The Solanaceae has a worldwide distribution and is one of the world's most economically important plant families, including the tomato, potato, eggplant, chili pepper, petunia, and tobacco as well as lesser-known species with potential uses as foods or medicines. It provides opportunities to investigate the interactions of plants with people, the evolution of domesticated species, and character changes associated with human selection.
