Research Interests
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.
