Expertise and areas of study:

Dr Joyce McBeth’s expertise is in microbial interactions with the geosphere including metal(loid) and hydrocarbon contaminant remediation and metal transformations mediated by microbes in mine wastes. Her current research includes studies of microbes in mine tailings and ores and wastewater treatment systems and synchrotron approaches applied to mine-related remediation.

Prior to joining the University of Regina, Dr. McBeth was an Assistant Professor at the University of Saskatchewan (2015-2020), a Research Scientist at the Canadian Light Source synchrotron (2012-2015), and a Postdoctoral Researcher at Bigelow Laboratory for Ocean Sciences (2008-2012).

Dr. McBeth is co-chair of the Saskatchewan Branch of the Canadian Geoscience Educators’ Network (CGEN).

Courses taught:

I taught the following courses in my previous appointment (prior to my arrival at the University of Regina in summer 2020). I will likely develop University of Regina courses along these lines too, after strategic discussions with other faculty members in our department. Students: let me know if these look interesting to you! – Dr McBeth

Introduction to Geomicrobiology: Exploration of the role of microbes in geochemical and mineral transformations in natural environments and in engineered environments such as mine tailings and contaminated sites. Strong emphasis on environmentally-important microbial metabolic guilds and exploring the relationship of these guilds to biogeochemical cycles. Topics will include microbial diversity, microbial metabolism, cell surface reactivity and metal sorption, biomineralization, biosignatures, and culture-dependent and independent techniques in geomicrobiology.

Introduction to Organic Geochemistry: This course will provide students with an understanding of theory, practice and methods in organic geochemistry. The course will focus on the origin and distribution of organic matter in the environment, and its fate in natural and engineered environments. Topics will include carbon biogeochemistry, origin and characteristics of natural organic matter, organic matter in the rock record, molecular biomarkers, evolution of organic compounds in petroleum and contaminated sites, and analytical tools. Course content will centre around applications of organic chemistry in the study of earth history, economic geology, and natural and contaminated environments.

Graduate courses: Advanced Geomicrobiology, Advanced Organic Geochemistry. I run readings courses on these topics that include weekly journal club style presentations from the class participants to practice critical thinking and presentations skills, and a proposal assignment where we work to improve students' iterative writing skills. This course is a remote-learning inter-institutional offering with students participating at URegina and USask. In addition to students taking the course for credit, I have had several students officially or casually auditing this course. Suitable for graduate students in geology, biology, or environmental engineering programs.
