Research interests:

A central theme in my research is the evolutionary ecology of plant reproduction. We investigate the dynamics of different reproductive strategies and how plants interact with their biotic and abiotic environment through their reproductive system. Much of this work involves mating system and germination studies. Currently, we are investigating the dynamics of heterocarpy, a reproductive system in which different flowers on the same plant produce two or more types of fruits that have dramatically different dispersal and germination features. This reproductive strategy provides bet-hedging against habitat variation and may provide protection against seed loss through insect herbivory. This work focuses primarily on the genus Grindelia (gumweeds) and we are pursuing new directions related to its seed bank dynamics. . My lab is also conducting conservation research on the rare, riparian tree Alnus maritima (seaside alder), which grows in Oklahoma, Georgia, and the Delmarva peninsula. We are combining population genetic and ecological studies to investigate why this species has little establishment of new individuals from seed despite very high seed production. Response of this species to climate change is a topic of central interest for future studies.
In addition to the research described above, I also conduct science pedagogy and education research investigating how a curricular structure based on Tree-Thinking helps students understand concepts of biological evolution. I have also co-authored three high school level reference books: Plant Ecology, Plant Diversity, and Natural Section.
