Education & Training History
Dr. Richard Summerbell began his scientific career at the University of British Columbia in 1979 with an MSc thesis on the ecology and genetics of the basidiomycetous yeast Leucosporidium scottii. He was supervised by Prof. Robert J. Bandoni. He next studied under Prof. David Malloch at the University of Toronto and in 1985 completed a PhD thesis on the microfungal ecology of the rhizosphere of black spruce mycorrhizae. He did postdoctoral work with Prof. Julius Kane at the Ontario Ministry of Health under the auspices of the University of Toronto, and then, after receiving training in molecular genetics at the laboratory of Prof. James Anderson at U. Toronto, returned to the Ministry as a research scientist in 1988. He became chief mycologist for the Ministry in 1990 and continued to 2000. In 2000 he moved to become senior researcher and group leader for the CBS Fungal Biodiversity Centre (Centraalbureau voor Schimmelcultures), a branch of the Royal Netherlands Academy of Sciences in Utrecht, the Netherlands. In 2007 he accepted the position of Research Director with Sporometrics Inc.
Dr. Summerbell is recognized as one of the world’s foremost experts on fungi affecting human and environmental health. He is the author of over 140 peer-reviewed scientific papers on fungi and bacteria, and is also the co-author of two popular laboratory manuals, Identifying Filamentous Fungi (G. St. Germain and R.C. Summerbell, Star Publishing, 1996) and Laboratory Handbook of Dermatophytes (J. Kane, R.C. Summerbell et al., Star Publishing, 1997). He is a recognized expert in three areas, indoor mycology, medical mycology and soil mycology. In indoor mycology, he is best known for contributing major chapters to books such as Microorganisms in home and work environments (edited by B. Flannigan, R. Samson and J. D. Miller. Harwood Academic Publishers, Amsterdam, 2001) and Allergic bronchopulmonary aspergillosis (edited by V.P. Kurup and A.J. Apter, 1998), as well as for co-authoring Canada’s influential guidelines for air quality in public buildings, Fungal contamination in public buildings: A guide to recognition and management (Health Canada, 1995). In medical mycology, apart from the textbooks listed above, he is best known for research on dermatophyte evolutionary systematics; Fusarium, Phaeoacremonium and Phialemonium species involved in human opportunistic infections; and diagnosis of onychomycosis. In soil mycology, he is an authority on the mycology of forest tree roots and recently served as principal editor of The missing lineages: phylogeny and ecology of endophytic and other enigmatic root-associated fungi. (Studies in Mycology vol. 53). He has also recently co-developed a body of ideas on how plant pathogens may evolve to become human pathogens. Dr. Summerbell served as the editor-in-chief of the journal Medical Mycology from 1999-2003, and has also been an associate editor of that journal as well as Studies in Mycology and Mycopathologia. In addition, he served for 10 years as an editorial board member of the Journal of Clinical Microbiology.
