Most of my research has focused on the systematics of Calyceraceae and the basal members of Asteraceae (sunflower family). Systematics uses a wide range of data to classify and examine evolutionary relationships of a group of organisms. For my studies I have used morphology, pollen structure, wood anatomy, cytology, and distribution of Calyceraceae to understand the evolution of this small southern South American family of flowering plants. My work with Calyceraceae has extended into looking at large scale patterns of evolution in Asteraceae.

Current projects being prepared for publication in this area include the following: 1) cytological survey of the family; 2) pollen ultrastructural study of the family and 3) taxonomic revisions of genera within Calyceraceae.

A second area of research has been in the area of angiosperm paleobotany. Most of my studies have focused on the Catahoula formation of east Texas. This Oligocene age flora is significant not only because of its age, but also because of the array of fossil Fagaceae (oak family) found at the locality. In particular, I have been looking at an unusual fruit type associated with the Fagaceae and fossil Taxodium.

In Georgia I have been looking at an Eocene paleosol in conjunction with Dennis Parmley's studies of fossil vertebrates at Gordon. No paleosols have been described in association with kaolin deposits in central Georgia. The description of this paleosol will give some insights into interpreting some of the unusual arrays of fossil vertebrates recovered from the Gordon site.
