Research and/or Creative Works

Weston Testo and Michael Sundue in the fieldMy research program seeks to discover and describe biological diversity. I am broadly interested in land plants, with a particular focus on the ferns and lycophytes. Major goals include discovering and describing biodiversity, and understanding how particular traits are distributed across the tree of life.  My research falls into five main areas: 1) phylogenetics and biogeography 2) morphological trait evolution and diversification 3) generic circumscription and taxonomic revision 4) macroevolution, with an emphasis on the correlates of diversification rates, and 5) floristics with an emphasis on developing web-based tools for the dissemination of results. Many of these questions are best addressed by consulting herbaria and conducting field work, and therefore herbarium activities and collecting expeditions are central to my research. 

At UVM I am co-leader of the Barrington-Sundue lab. My other duties include curation and development of both the Pringle Herbarium, and the Tryon Pteridophyte Library. I also maintain a photo blog of ferns and lycophytes with Nathan Smith (Instituto Nacional de Pesquisas da Amazônia).
