Education & Background
- Postdoctoral appointment, Harvard University Herbaria
- Postdoctoral fellowship, Harvard University Center for the Environment
- Ph.D. in Biology, Duke University
- A.M. in Organismic and Evolutionary Biology, Harvard University
- B.S. in Ecology, Evolution and Behavior, University of Minnesota, Twin Cities
My research is generally concerned with understanding how changing environments shape plant diversity on both evolutionary and ecological time scales. Currently, I am focused on using historical specimen data to study how historic climate change (over the past century) has impacted plant phenology and diversity across North America.
