Area of Interest and Research
The biology of ferns, especially systematics and evolution, biogeography, and population genetics.
Current Activities/Research Program
- Reconstructing the phylogeny of the fern family Polypodiaceae using a combination of features from DNA sequencing, morphology, and biogeography. I am collaborating on this study with Drs. Tom Ranker (University of Colorado, Boulder) and Alan Smith (University of California, Berkeley).
- Studying patterns and processes of speciation in ferns using analysis of breeding systems, population biology, and ecology. Focusing on patterns of ecology and biogeography provides hypotheses of change over space and time that can be tested. I anticipate continuing these investigations. I am also interested in the impact that polyploidy has had on fern genomes and studying how the genetic systems of ferns have been influenced by their polyploid histories. Finally, I am pursuing revisions of the genera that constitute the reconstituted family Polypodiaceae.
