This research has resulted in the discovery of three new species of Solanum from Ecuador. The section consists of viny plants that root at the nodes. I am currently working on a revision of Solanum section Herpystichum, one of the most poorly known and undercollected of these groups. This study is in its preliminary stages, but the potato clade consists of five major groups: section Anarrhichomenum section Basarthrum section Herpystichum and section Pteroidea and a strongly supported clade composed of sections Petota (containing the potato), Lycopersicon (containing the tomato), Lycopersicioides, Juglandifolium, and Etuberosum.ĭespite the intense research focused on potato and its close relatives, other parts of the "potato clade" are very poorly known. The purpose of this study is to use DNA sequences from the nuclear and chloroplast genomes to resolve relationships among the groups that make up the potato clade and to identify morphological traits that make each of the groups easily identifiable in the field. ![]() Most of the 200-300 species in the potato clade belong to a group of species closely related to tomato and potato and, as a result, are the focus of intense research however, the clade contains four other smaller groups that remain virtually unknown and relationships among all of these groups are poorly understood. The potato clade is exclusively New World in distribution, with most groups centered in the Andes of South America. muricatum), it is one of the most economically important clades of plants in the world. The informally named “Potato Clade” is one of 12-15 well-supported major clades within Solanum, and since it includes the potato ( S. With over 1000 species, the genus Solanum presents the opportunity to work on both large and small-scale questions within the same group of plants. ![]() I am currently working on the taxonomy and evolutionary relationships of the giant genus Solanum. In my research into plant systematics I make use of both traditional and contemporary techniques to study evolutionary relationships among species, morphological evolution, and the diversification of plant groups in both space and time.

Plant systematics, including taxonomy, phylogenetics, biogeography, and diversification of “giant genera” – those with over 1000 species – including Piper (Piperaceae) and Solanum (Solanaceae).
