After a short stint as an NSERC Visiting Fellow with Agriculture and Agri-Food Canada, Stephen accepted a faculty position at the University of Alberta, where his research focus is on diseases of field crops with an emphasis on clubroot of canola. He has authored or co-authored nearly 200 peer-reviewed papers, as well as many research reports and extension articles. Stephen is active in undergraduate and graduate student teaching, and has supervised or co-supervised the successful completion of 33 Master’s and Doctoral theses. Dr. Strelkov has received the ‘Outstanding Young Scientist,’ ‘Outstanding Achievements in Plant Disease Management,’ and ‘Outstanding Research’ awards from the Canadian Phytopathological Society, and was a Killam Annual Professor at the University of Alberta. He serves as Editor-in-Chief of the Canadian Journal of Plant Pathology.

Dr. Mary Ruth McDonald
Dr. Mary Ruth McDonald is a professor at the University of Guelph. She conducts basic and applied research on crop protection and integrated pest management of vegetable crops, with emphasis on onions and carrots, and also has an extensive research program on the disease clubroot, of canola and Brassica vegetables. Her work on crop protection incorporates conventional and biological crop protection materials, in addition to host resistance and cultural controls such as crop rotation and solarization.

Dr. Sabine Banniza
Dr. Sabine Banniza is a professor of plant pathology at the Crop Development Centre of the University of Saskatchewan, Canada, where she has been working on pulse crop diseases for more than 20 years. Much of her research has focused on understanding host-pathogen interactions of pulse crops and their implications on population dynamics, resistance breeding and disease management. A considerable amount of research has concentrated on foliar fungal diseases, in particular the pathogen Colletotrichum lentis of lentil, whose genome was sequenced and whose interaction with lentil has been dissected. Recently, her group has also commenced work on emerging root rot pathogens, particularly Aphannomyces euteiches and Fusarium spp. with the objective to identify durable resistance in pea, lentil and chickpea.

Dr. Bruce Gossen
Dr. Bruce D. Gossen graduated with a Ph.D. in plant pathology from the University of Saskatchewan in 1985. Since then, he has been employed as a research scientist with Agriculture & Agri-Food Canada at Saskatoon SK, specializing in management of diseases of field crops. Over the course of his career, he has worked on diseases of forages and turf, cereals, pulse crops, canola and even vegetables. He has published more than 200 papers in refereed journal, plus hundreds of other articles and presentations. He has had a leadership role in many organizations, including a term as President of the Canadian Phytopathological Society, and has received numerous awards for his work, including two Golden Harvest Awards from AAFC, the Award for Outstanding Research from the Canadian Phytopathological Society, and became a Fellow of the CPS in 2019. He currently leads studies on clubroot of canola and on root rot of field pea with colleagues across Canada and the USA, and continues to be active in supervision of graduate students and mentoring post-doctoral fellows.

Dr. Tahera Sultana
Dr. Tahera Sultana is a research scientist and a nematologist for the London Research and Development Centre (LRDC)-Vineland, Agriculture and Agri-Food Canada. She earned her PhD degree from Chungbuk National University, Republic of Korea. Her research is focused on understanding the importance of cover crop use and rotation in different crop management systems considering nematode as bio-indicator, characterizing nematode communities under different crop management systems on soybean production, identifying and characterizing nematode as a causal agent and their involvement on fruit tree decline, finding the efficacy of different chemicals against plant-parasitic nematodes on greenhouse fruits and vegetables and developing molecular markers to identify nematodes at the species level.

Dr. Joji Muramoto
Dr. Joji Muramoto is an assistant Cooperative Extension organic production specialist at the University of California Agriculture and Natural Resources (ANR). He is the first specialized that University of California Cooperative Extension hired to focus on organic agriculture. Dr. Muramoto coordinates a statewide program focused on fertility and pest management in organic production systems across the state. He has a joint affiliation with UCCE and the Department of Environmental Studies and the Center for Agroecology and Sustainable Food Systems (CASFS) at UC Santa Cruz.

Dr. Muramoto
Dr. Muramoto, who is fluent in Japanese, is also an affiliate professor in the Department of Agricultural Chemistry, Tokyo University of Agriculture, Japan.
Prior to joining ANR, Dr. Muramoto served in multiple capacities at UC Santa Cruz. Since 1996, he has conducted research and extension on fertility and soil-borne disease management in organic and conventional strawberry and vegetable production in coastal California. Over the course of his 32-year career as a soil scientist/agroecologist, Dr. Muramoto has secured and managed over $11 million of external grants as a principal investigator or co-PI, conducted numerous field-based research projects, published 39 peer-reviewed or invited papers or book chapters including several multidisciplinary papers, supervised more than 100 undergraduate student workers and interns, and given more than 90 extension presentations in California.
