As a fern loving polymath, my research spans many disciplines in an attempt to increase the understanding  of the Onoclea sensiblis, the Sensitive Fern. 

Onoclea is quite an interesting fern, from its dimorphic morphology to bizarre reproductive habits, but I am most interested in it's huge global distribution. As shown below, we see that this fern has a disjunct distribution, with two separate populations in East Asia and Eastern North America. Specifically, I want to know the origin, past range shifts, and environmental constraints of this far flung fern. This involves a three prong approach integrating Ecophysiology, Molecular Genetics, and Biogeography to answer fundamental ecological and evolutionary questions.
