Schizaphis graminum winged aphid


My long-term interests are in the evolution of biological complexity, such as that apparent in complex life histories, in intimate interactions among species, and in species-diversity of clades and communities.

My focus is on symbiosis, particularly that between multicellular hosts and microbes.
