Horizon Postdoctoral Fellowships

A lipidomics approach to tracking hypoxia in the St. Lawrence Estuary

Reference number: 7004
Supervisor: Yves Gélinas

Program description

The St. Lawrence Estuary (SLE), a vital ecosystem for eastern Canada, is severely affected by the discharge of organic matter and inorganic nutrients from human and natural sources, leading to perennially hypoxic conditions in its bottom waters. The severity, frequency and spatial scale of hypoxia have increased in the past few decades causing the mass mortality of marine animals, benthic defaunation, loss of biodiversity, and a decline in fisheries production. In this project, we propose to exploit a combined lipidomics (high-resolution LC-MS) and isopotomics (compound-specific stable [13C/12C, D/H] and radio [14C] isotope analysis) approach to identify the relative importance of the different processes that are responsible for the continuous decrease in dissolved oxygen concentrations in the bottom waters.

Academic qualifications required

PhD in Chemistry or related fields, with experience in Biogeochemistry and Stable Isotope methods and instrumentation.

Eligibility requirements

  • Applicants must not currently hold a postdoctoral appointment at Concordia
  • Priority will be given to postdoctoral fellows who have obtained their PhD from another university although in exceptional cases Concordia graduates may be considered
  • Applicants must adhere to the postdoctoral fellow eligibility criteria outlined in Concordia University’s Postdoctoral Policy


Horizon position is expected to be filled as soon as possible but no later than March 1, 2024.

Submission process

  • All documents must be submitted to Niyusha Samadi
  • Please include the reference number with your application

Application checklist

  • One to three (1-3) page research statement demonstrating fit with the program described above.
  • Current curriculum vitae demonstrating research excellence and a capacity for leadership in the domain (maximum 5 pages).
  • Two letters of reference from academic supervisors or current employers to be sent via e-mail directly to Niyusha Samadi.


The prestigious two-year Horizon Postdoctoral Fellowships are valued at $50,000 per year plus benefits and full access to Concordia’s services, including GradProSkills.
