معرفی
Dr. Joyce McBeth is an Assistant Professor in the Department of Earth Sciences within the Faculty of Science at the University of Regina. Her research focuses on geomicrobiology, microbe-mineral interactions, environmental microbiology, and metal biogeochemistry, particularly in mine waste and contaminated environments. She employs advanced synchrotron techniques to study microbial processes involved in contaminant remediation and metal transformations.
Her research interests span microbial interactions with the geosphere, including metal(loid) and hydrocarbon contaminant remediation, microbially mediated metal transformations in mine wastes, and the application of synchrotron-based methods to environmental problems. She investigates microbial communities in mine tailings, ores, and wastewater treatment systems, with emphasis on Fe- and Mn-oxidizing bacteria and their roles in biogeochemical cycling.
Her recent publications reveal a strong trend in environmental geochemistry and geomicrobiology, particularly in the areas of arsenic and uranium speciation, iron and manganese biogeochemistry, microbial community dynamics in extreme environments, and the use of synchrotron X-ray techniques for molecular-level analysis. These works highlight her interdisciplinary approach combining microbiology, geochemistry, and environmental engineering.
Dr. McBeth has taught undergraduate courses such as GEOL 102 (Environmental Geology), GEOL 170 (Introductory Environmental Geoscience), GEOL 201 (Internal Processes of the Earth), and GEOL 429 (Glacial Geology), as well as graduate-level GEOL 880AG (Advanced Geomicrobiology). She also co-teaches inter-institutional graduate reading courses in geomicrobiology and organic geochemistry involving students from both the University of Regina and the University of Saskatchewan.
Her scientific contributions are documented in high-impact journals including Environmental Science & Technology, Frontiers in Microbiology, Chemical Geology, and Geochimica et Cosmochimica Acta.
Dr. McBeth has mentored graduate students through journal clubs and proposal-writing exercises in advanced geomicrobiology and organic geochemistry courses. She collaborates extensively on projects related to mine waste remediation, groundwater contamination, and microbial biogeochemistry. Her prior experience includes an Assistant Professorship at the University of Saskatchewan (2015–2020), a Research Scientist position at the Canadian Light Source synchrotron (2012–2015), and postdoctoral research at Bigelow Laboratory for Ocean Sciences (2008–2012). She is actively involved in developing new courses and research initiatives at the University of Regina.
