Research topics: Plant systematics, molecular phylogeny, reproductive biology, and quantitative morphology
Research program: I study plant systematics, reproductive biology, and phylogeny, with special emphasis on the Rosaceae (the rose family) and Pinaceae (the pine family), both of which contain ecologically important plants. Along with collaborators, I am interested in the molecular phylogeny of these families based on sequences from multiple genes and structural data. We have a long interest in the evolutionary origin of and phylogenetic relationships within apple subfamily. We also study one of the genera of the rose family, Amelanchier (the shadbushes or serviceberries) which has long challenged systematists with its unclear species boundaries and complex patterns of morphological variation. These small trees and shrubs also provide a model for the evolution of apomixis (asexual seed production). Research goals include identifying the relevance of apomixis and polyploidy to patterns of variation, understanding the biology of apomixis, establishing a workable species concept, and developing a tractable species classification. Research techniques include field studies, DNA sequencing, phylogenetic analyses, quantitative morphology, and studies of breeding systems. In Pinaceae, my primary focus has been phylogeny of species in the spruce genus (Picea). Graduate students I have advised have used these techniques to study problems in these groups and other groups as well.
