1978 – Ph.D., Indiana University
My research interests are in higher plant systematics with a focus on members of the sunflower family (Asteraceae).
Molecular Phylogenetic Analysis of Eupatorieae
A collaborative study being carried out together with Dr. Jose L. Panero of the University of Texas involves a systematic analysis of tribe Eupatorieae. This large group is primarily restricted to the New World, where it has produced an amazing amount of species-level diversity. Molecular phylogenetic analyses are being carried out with the goal of resolving issues of classification, and assessing the morphological changes associated with the success of this group.
Systematic Studies of Helianthus
The genus Helianthus comprises approximately 50 species native to North America, and includes the agronomically important common sunflower, Helianthus annuus. Currently the focus of my studies are on the perennial species of the genus, with a particular emphasis on resolving issues of classification and working out the relationships of some of the polyploids, such as H. hirsutus, H. strumosus, and H. tuberosus.
Other Research in my Laboratory
Phylogenetic Analyses of Asteraceae of eastern North America – deciphering the relationships among species in the larger and more diverse genera of Asteraceae in eastern North America has proven to be challenging. Studies of Helianthus, Liatris, Eupatorium, and Solidago have revealed each to have a relatively low level of variability at the molecular level. We are seeking to find markers with an appropriate level of variability to help understand the causes for the contrasting high amount of species level diversity compared to the apparently low amount of genetic divergence.
