Canada Research Chair (Tier 2)

Canada Research Chair (Tier 2) in Exposure Science and Environmental Risk

2023-11-27

The University of Saskatchewan (USask) and School of Environment and Sustainability (SENS) are pleased to invite applications for a Tier 2 Canada Research Chair in Exposure Science and Environmental Risk. The Canada Research Chairs Program is the flagship of a national strategy to make Canada a world-leading country in research and development.

Chemical contamination of the environment and the resulting health impacts on humans, animals, and other biota represent one of the major challenges of the 21st century. Assessing the cumulative risk associated with environmental contaminants requires an integrative and accurate assessment of exposure and hazard. However, in the face of ever-increasing complexity in dynamics of exposure (e.g., complex mixtures, time-variable exposure, climate, and land-use change) and drivers of hazard (e.g., multiple stressors, interactive effects, physiological status), this task has become increasingly difficult. Therefore, advances in the field of exposure science require a holistic understanding of the abiotic and biotic processes that drive external exposure, uptake into biota, internal distribution, target site activity, and the interaction of chemicals.

This CRC in Exposure Science and Environmental Risk aims to attract an interdisciplinary scientist that is uniquely qualified to advance the field of exposure science by fusing modern systems biology approaches with advanced analytical technologies for advanced risk assessment. The ideal candidate will work at the intersection of biology and chemistry, will use cutting-edge technology and approaches to advance the science of chemical exposure in toxicology, and will synergize the current world-class expertise in environmental toxicology and chemistry at the University of Saskatchewan.

The successful nominee will initiate and lead an innovative and impactful program of research, foster extensive interdisciplinary and multi-sector collaborations, and raise the profile and impact of USask through an innovative research program and knowledge mobilization within and beyond academia. The academic home of this position will be in SENS and the chair would be based in the Toxicology Centre.

MSc or PhD - Effects of
diluted bitumen on early life stage salmon

2023-09-19

An international team of ecotoxicologists, chemists, and engineers have come together to better understand the effects of pipeline oil spills in Canada’s west coast rivers on chinook salmon (Oncorhynchus tshawytscha ). This ambitious research program involves simulating spills of diluted bitumen in outdoor experimental rivers at the Quesnel River Research Center (QRRC) in British Columbia. This study will answer whether residual oil trapped in salmon rearing
habitats impairs the health and survival of chinook embryos and alevins. Students will be co-supervised by Dr. Diane Orihel and Dr. Jason Raine.

The student will conduct a thesis project based at the QRRC on the effects of diluted bitumen on early life stage salmon.

MSc or PhD - Toxicity of sulfolane to amphibian

2023-09-19

Dr. Ryan Prosser’s research group is searching for a graduate student to work on a NSERC Alliance project that is a collaboration between the University of Guelph, University of Waterloo, Shell Canada, Matrix Solutions, and Azimuth Consulting Group. The project will involve investigating the toxicity of sulfolane to different early life stages of amphibian species. Sulfolane (also tetramethylene sulfone, systematic name: 1λ6-thiolane-1,1-dione) is an organosulfur compound with the formula (CH2)4SO2. It is a colorless liquid commonly used in the chemical industry as a solvent for extractive distillation and chemical reactions. There is a lack of toxicity data on sulfolane for amphibians. This data is important for assessing the potential risk that sulfolane contamination poses to amphibian populations and, by extension, freshwater ecosystems.

MSc Opportunity

MSc in PFAS and Pharmaceuticals in Arctic Wastewater

2023-06-25

Seeking an MSc student to characterize the concentrations, fate, and sources of
per- and polyfluoroalkyl substances (PFAS) and pharmaceuticals related to wastewater
in the Canadian Arctic. The study site is the wastewater lagoons and associated flow
path for the community of Baker Lake, NU. The student will use cutting edge analytical
techniques, specifically ultra-high performance liquid chromatography-triple quadrupole
mass spectrometry and high-resolution mass spectrometry, which they will be trained
on. They will gain field and sampling experience, including working with and developing
novel passive samplers. Measurements of PFAS and pharmaceuticals along the flow
path and in reference locations will help to understand the effectiveness of current
treatment, as well as help to better understand possible human and ecological risks.

Watershed Biogeochemist Laboratory Technican

2023-04-20

The Watershed Biogeochemistry in the Anthropocene Lab (http://gersonlab.weebly.com) at Michigan State University (MSU) is seeking applications for a laboratory technician position to start in September 2023. This technician will work on a funded collaborative project between MSU, the University of Colorado Boulder, and the University of California Santa Cruz focused on investigating the interaction of agricultural sulfur runoff and mercury methylation in California vineyards and nearby wetlands.

Impacts of QACs on boreal lake benthic and emergent insect communities: Linking the molecular to the community

2023-04-17

Seeking a motivated, enthusiastic, and dedicated PhD student to investigate how quaternary ammonia compounds (QACs) can impact the benthic and emergent insect communities of boreal lakes. The student will use traditional taxonomy combined with eDNA and RNA Seq approaches to examine changes at the molecular, individual, population, and community-levels. The student will collaborate with a large number of researchers and students as part of a larger project that will examine the fate and effects of QACs on whole lakes at the IISD Experimental Lakes Area.
