Position Summary

The Postdoctoral Fellow will advance the River Institute’s research and applied science capacity in environmental DNA (eDNA), supporting biodiversity monitoring, species-at-risk recovery, invasive species detection, and ecosystem health initiatives in the St. Lawrence River and broader Great Lakes–St. Lawrence watershed. The Fellow will lead and/or co-lead the development, validation, and application of molecular assays (e.g., qPCR/ddPCR and/or metabarcoding workflows), contribute to study design and field sampling strategies, manage and analyze eDNA datasets, and translate findings into peer‑reviewed publications, technical reports, and partner-ready outputs. The role is highly collaborative, working closely with River Institute staff and external partners (e.g., academic collaborators, government agencies, and Indigenous partners) to ensure rigorous, ethical, and impactful science.

Key Responsibilities

Research leadership (eDNA methods): Lead development and optimization of eDNA laboratory workflows, including assay design, validation, and performance evaluation (e.g., sensitivity/specificity, inhibition testing, controls, contamination prevention). Assay development: Design and validate species-specific primer/probe assays (e.g., for species at risk and invasive species) and/or metabarcoding marker panels, as appropriate to project needs. Project delivery: Contribute to study design, sampling plans, and timelines; coordinate day-to-day research activities to meet internal and external deliverables. Field integration: Support and/or participate in field sampling for eDNA and complementary monitoring (e.g., fish community surveys), including chain-of-custody and sample handling best practices. Data management and analysis: Curate, analyze, and interpret eDNA datasets; develop reproducible workflows for data processing and statistical analysis; produce clear figures, tables, and summaries. Quality assurance: Contribute to documentation and standard operating procedures (SOPs) that support robust laboratory practice; follow applicable health and safety and biosafety requirements. Knowledge mobilization: Prepare peer‑reviewed manuscripts, conference presentations, and partner-facing reports/briefing materials; communicate results to technical and non-technical audiences. Grant and proposal support: Contribute to funding applications and project proposals (methods, work plans, budgets/justifications where applicable) and support partnership development. Training and mentorship: Provide guidance and mentorship to students, interns, and staff engaged in eDNA work; support training activities for collaborators as needed. Collaboration: Work collaboratively with internal teams and external partners to align research outputs with program priorities and community/partner needs.

Required Qualifications

PhD completed within the last 5 years (or near completion at time of appointment) in biology, ecology, conservation genetics/genomics, molecular ecology, environmental sciences, or a related field. Demonstrated experience with eDNA methods and molecular techniques (e.g., DNA extraction, qPCR, library preparation and sequencing workflows, primer/probe design, contamination control). Strong quantitative and analytical skills, including experience with statistical analysis and reproducible workflows (e.g., R and/or Python). Track record of scientific writing (e.g., peer-reviewed publications, thesis chapters, technical reports) and the ability to communicate complex results clearly. Ability to work independently, manage multiple priorities, and deliver results on schedule in a collaborative environment. Excellent interpersonal skills and ability to work respectfully with diverse partners, including community and Indigenous partners. Valid driver’s licence and ability to travel for fieldwork/meetings as required (or willingness to obtain prior to start date).

Preferred Assets

Experience with qPCR and/or targeted capture/metabarcoding bioinformatics pipelines (e.g., DADA2/QIIME2 or similar). Experience designing and validating assays for species-at-risk monitoring and/or invasive species detection in freshwater systems. Familiarity with QA/QC frameworks (e.g., ISO 17025-aligned documentation, laboratory information management systems, chain-of-custody procedures). Experience collaborating across organizations (e.g., universities, government agencies, NGOs) and contributing to partnership-based research programs. Experience contributing to grant writing and/or leading components of funded research projects. Experience with field sampling in aquatic environments and/or integrating eDNA with complementary monitoring methods.

Working Conditions & Requirements

Work will include laboratory and office-based duties, with periodic fieldwork in variable weather conditions and occasional work outside standard hours during field seasons or project deadlines. Must be able to follow laboratory health and safety requirements, including safe handling of chemicals and biological materials; WHMIS training (or willingness to complete). Ability to perform tasks requiring manual dexterity and sustained attention to detail (e.g., pipetting, sample processing). Use of personal protective equipment (PPE) as required. Occasional travel for partner meetings, workshops, conferences, and field sites.

Reporting Relationships & Collaboration

The Postdoctoral Fellow (eDNA) will report to the Program Leader, Research & Technical Services (or designate) and will work closely with the Analytical Services & QA/QC Officer for day-to-day coordination of laboratory operations, as applicable. The Fellow will collaborate with River Institute research staff and external partners, including academic collaborators, government agencies, and Indigenous partners.
