Chromosome Evolution, Hybridization, Speciation

Statement
My research interests focus on biosystematics, speciation, and adaptive radiation in plants. Most of my work has involved chromosome evolution in a group of closely related Pacific Coast and Hawaiian genera that include the well-known Haleakala silversword. However, I am also collaborating with a number of other researchers on such aspects as molecular evolution, physiological diversification, and phytochemistry of these taxa. Our goal has been to provide a comprehensive, multidisciplinary perspective on the spectacular adaptive radiation that characterizes the Hawaiian element of this group.
