I am a fungal evolutionary biologist. I am particularly focused on the diverse and beautiful mushroom-forming Fungi (Agaricomycetes). I have been a collaborator in the NSF-supported Assembling the Fungal Tree of Life (AFTOL) project, which has worked to develop a higher-level phylogenetic framework for the Fungi. I am also participating in comparative genomics studies through the DOE_supported Fungal Genomics Program, which are aimed at understanding the genetic bases of transitions between decayer and mycorrhizal (symbiotic) lifestyles. One of my long-term interests is fungal systematics, and the translation of phylogenetic trees into classifications. I have also dabbled in paleomycology and fungal developmental biology. I am a Professor in the Biology Department of Clark University and I am currently the President of the Mycological Society of America. To learn more about my interests, please visit my lab website.
