My research focuses on integrated molecular and morphological phylogenetic studies of land plant diversity and evolution; polyploidy and apomixis in ferns; reconciling molecular rate heterogeneity with life history patterns; strategic planning for collections-based institutes, especially herbaria

I use cytogenetics to understand plant evolution. My research focuses on many taxonomic groups, but especially ferns, and various genera of the mustard family (Brassicaceae), mostly Boechera
and Draba. Complex patterns of reticulate evolution revealed by chromosome work are resolved by also integrating information from morphology, molecular systematics and reproductive biology.

I am broadly interested in fern phylogenetics, with a focus on the adiantoid clade (Pteridaceae). In particular, I am obsessed with demonstrating the monophyly of Adiantum, and plumbing the complexities of cheilanthoid evolution. I also like Gilligan.
I am excitedly working on uncovering the mechanism of nutrient exchange in the intricate symbiosis between the small aquatic fern Azolla and its obligate N2-fixing cyanobacterium, Nostoc azollae. For more information please check out my website.
I have broad interests in plant systematics, anatomy, and microscopy. My current research is focused on the function and evolution of “farina” (waxy flavonoid exudates on leaf surface) in the desiccation-tolerant fern clade notholaenids (Pteridaceae). Please also visit my website.
I am broadly interested in the Andes as a region, especially how diversification and evolution have occurred in the dry Inter-Andean valleys. I’m keen on understanding biogeographical patterns and the effects that varied reproductive strategies (polyploidy, apomixis, various levels of selfing) have had on diversification. For more information, and for my past life, please visit my website.
