PhD Position: Slow-Release Biostimulatory Solution Development for Hydrocarbon Remediation
Supervisor: Dr. Steven Siciliano, Professor of Soil Science and Toxicology
Are you passionate about developing sustainable remediation technologies that can transform contaminated site management across Canada? Join our research team to lead the development of innovative slow-release biostimulatory solutions that could triple the number of sites being actively remediated.
Project Overview: You will evaluate the effectiveness of replacing proven ingredients in our established BioLodestone IRC solution with slow-release counterparts, including struvite, basalt, polymer-coated nitrate fertilizers, and Fe-EDDHA. Your research will progress from bench-scale evaluations to ex-situ soil bag experiments (~1 m³ each), and potentially culminate in full-scale field trials at contaminated sites across Western Canada.
Why This Position?
- Work directly with Federated Cooperatives Limited (FCL), managing ~1,000 sites of concern across Western Canada
- Quarterly meetings with industry partners and environmental consultants
- Hands-on field experience implementing remediation programs at contaminated sites
- Opportunity to translate research directly into industry practice within years
- Access to state-of-the-art facilities at one of Canada's leading soil science departments
- Weekly meetings with Dr. Siciliano and monthly interactions with FCL's environmental team
Ideal Candidate:
- Background in soil science, environmental science, microbiology, or related field
- Interest in applied environmental research and remediation technologies
- Strong analytical and experimental design skills
- Enthusiasm for fieldwork and industry collaboration
Training Benefits:
- Publication and conference presentation mentorship
- Professional development in business communications and industrial timelines
- Experience in regulatory compliance and stakeholder engagement
- Exposure to North America's largest concentration of environmental toxicologists
MSc Position 1: Colloidal Suspension Development for Slow-Release Mineral Delivery
Supervisor: Dr. Steven Siciliano, Professor of Soil Science and Toxicology
Join our team to solve a critical formulation challenge: developing flowable colloidal suspensions of slow-release minerals that can be easily injected into contaminated soils for long-term biostimulation.
Project Overview: You will develop methods to create stable colloidal suspensions of slow-release minerals using various surfactants (including Span 20, Tween 20, Tween 80, and Poloxamer 124). Building on preliminary results showing promising suspension characteristics, you will optimize formulations to balance settling rate, flowability, and stability—making slow-release biostimulatory solutions practical for field deployment.
Why This Position?
- Bridge chemistry and environmental engineering in applied remediation science
- Direct collaboration with FCL, one of Western Canada's largest fuel suppliers
- See your formulations tested at real contaminated sites
- Quarterly technical meetings with industry consultants and FCL's environmental team
- Work in a world-class soil science research environment
Ideal Candidate:
- Background in chemistry, chemical engineering, environmental science, or related field
- Interest in colloid science, surfactant chemistry, or formulation development
- Strong experimental and analytical skills
- Enthusiasm for translating laboratory research to field applications
Training Benefits:
- Weekly individual and group mentoring sessions with Dr. Siciliano
- Quarterly feedback and professional development sessions
- Access to Central Analytical Laboratory facilities
- Industry networking and career development opportunities
MSc Position 2: Organic Acid Optimization for Enhanced Mineral Weathering in Contaminated Soils
Supervisor: Dr. Steven Siciliano, Professor of Soil Science and Toxicology
Are you interested in understanding how organic acids can accelerate mineral weathering to sustain long-term hydrocarbon remediation? This position offers the opportunity to optimize organic acid formulations that will enhance nutrient release from slow-release minerals at contaminated sites.
Project Overview: You will evaluate how organic acids (citric acid, maleic acid, tartaric acid, malonic acid, and oxalic acid) interact during the stimulation of weathering and remediation at contaminated sites. Your research will optimize organic acid concentrations to provide the desired release of nutrients at rates suitable for sustained biostimulation over multiple years.
Why This Position?
- Address a critical gap in long-term remediation technology
- Work with FCL on sites across Western Canada
- Research that directly responds to industry needs for decade-long groundwater protection
- Collaboration with environmental regulators and consulting companies
- Integration of geochemistry, microbiology, and remediation science
Ideal Candidate:
- Background in geochemistry, soil science, environmental chemistry, or related field
- Interest in mineral weathering, organic acids, and soil processes
- Strong analytical skills and attention to experimental detail
- Motivation to work on applied environmental problems
Training Benefits:
- Weekly mentoring with Dr. Siciliano (individual and group sessions)
- Exposure to field sampling, risk assessment, and advanced analytical techniques
- Quarterly presentations to industry partners
- Publication support and conference opportunities
- Access to Saskatchewan Centre for Cyclotron Science and specialized IRC laboratories
Application Information for All Positions:
The University of Saskatchewan is committed to equity, diversity, and inclusion. We particularly encourage applications from First Nations, Inuit, and Métis candidates, and will work with Indigenous communities to support student recruitment and retention, including identifying research sites near students' home communities where possible.
To Apply: Contact Dr. Steven Siciliano with your CV, transcripts, and a brief statement of interest explaining your background and motivation for the position.
Funding: Competitive graduate stipends provided through NSERC Alliance grant and FCL partnership.
