Meet the Staff
Dr. Timothy A. Block
The John J. Willaman Chair of Botany
My research interests are in the flora of Pennsylvania and in GIS mapping of plant distribution.
Dr. Ann F. Rhoads
Senior Botanist, Retired
My research interests are focused on the floristics of Pennsylvania. I want to document the natural vegetation of the state and better understand historical and contemporary influences that have shaped the patterns of plant distribution we see today.
Dr. Cynthia Skema
My research centers on the evolution and systematics of flowering plants, and involves the use of various tools to study their distribution, evolutionary relationships, morphology, anatomy and molecules. I am particularly interested in the floras of Pennsylvania and Madagascar, the digitization and dissemination of herbarium/floristics data, and the evolution of separate sexes in angiosperms. I specialize in the systematics of Malvaceae sensu lato, especially the dombeyoids.
