Research Interests

We might be experiencing an icehouse to greenhouse transition in the near future and I would like to understand the potential changes in plant cover that would occur in different climate realms.  To this end I am trying to study the previous icehouse to greenhouse transitions that occurred in the latest Carboniferous and Permian five times between 304 and 260 million years ago.  I am studying paleoclimatology, landscape reconstruction, paleoecology, plant taphonomy, and whole plant reconstruction (including morphology, anatomy, and taxonomy) for occurrences of plant fossils in localities of Carboniferous and Permian age in China, Peru, North America, and Europe.
