Research Interests

  • Evolutionary impact of landscape level disturbance and habitat fragmentation on plant species, particularly neotropical orchids.
  • Phylogeographic analyses for the purpose of identifying ancient refugia associated with Pleistocene glacial maxima and subsequent expansion zones of plant taxa in response to global warming.
  • Population genetic analyses of endemic and native plant taxa to investigate how long distance dispersal mechanisms and Pleistocene/Holocene climate change have influenced colonization of a young, isolated island chain and the evolution of species.
