My lab focuses on describing the ultrastructure, morphology and development of cells, tissues and organs in bryophytes, pteridophytes, and seed plants. These studies have generated new phylogenetic information and new insight into evolutionary modifications of cell architecture and ontogeny. I am currently a collaborator on the Green Tree of Life project and a PI on a hornwort biodiversity and biogeography project. My research team, the Green Morphology Group, includes graduate and undergraduate students who are involved in a variety of projects including ultrastructural studies detailing sperm cell development, fertilization in ferns, sporogenesis in bryophytes, and experimental studies to ascertain the role of the cytoskeleton in cell differentiation.
