Currently, I am studying the parsley ferns (Cryptogramma), a small, mostly circumboreal genus of ferns with 8-10 species. By synthesizing morphological, molecular and ecological data, I have produced a well-supported phylogeny of the genus.
Currently, I am reconstructing the pattern and tempo of two Alaskan species migrations after the Last Glacial Maximum and predict future range shifts or contractions caused by anthropogenic climate change.
I am also strongly interested in collections management and specimen digitization. For the last few years I have worked to advance these goals at the University of Alaska Museum Herbarium (ALA) and have helped to build our database of approx. 200,000 specimen records and high-resolution specimen images.
