Overview
I work as data manager in Duke University Herbarium. I maintain collections and databases of bryophytes and lichens, oversee a databasing project of bryophytes, and assist in training undergraduate and graduate students in bryophyte diversity and herbarium management. I'm an active member of Duke Bryophyte Laboratory where I participate on research in bryophyte systematics. I am interested in bryophyte diversity of montane, alpine and wetland ecosystems. I have extensive field experience in temperate and boreal regions of Europe and North America, with focus mainly on mosses and liverworts. Born and raised in the Czech Republic.
