Brief synopsis of current research:
My laboratory addresses a variety of ecological, taxonomic, developmental and cell biology themes associated with the biology of seaweeds. The primary focus of my current research is a symbiosis between the microscopic, haploid stages of kelp (Laminariales, brown algae) and red algae. The brown algae grow in the cell walls of the host, of which 17 species have been identified in western North America. We are currently trying to understand the nature of the interactions, the ecological significance of the symbiosis, and the role of host specificity and cell/cell interactions. Additional research includes studies of the introduced and highly invasive green alga Codium fragile in eastern Canada, apoptosis in red algae, and variation in DNA contents within plants of selected species of Laminariales (Laminaria saccharina and Alaria esculenta).
