Postdoctoral Researcher in Chemical Fingerprinting of Food

Website Food Toxicant Laboratory at McGill University

Tracking the Unique Fingerprint of Food

Proposed project title: “Harmonization of LC/MS based non-targeted fingerprinting workflows used for honey authenticity“. 

In a previous study, a robust, fast and innovative analytical tool was developed for the non-targeted analysis of contaminants in honey. The overall objective of the present research is to harmonize LC-MS based non-targeted fingerprinting workflows used for food authenticity, and develop a standard protocol for authenticity testing of honey.

In this context, the Postdoctoral Researcher will:

  • Run LC-QTOF-HRMS to establish the LCMS fingerprints for >300 honey samples obtained from the market and from various government and industrial partners.
  • Conduct controlled experiments to study the (non-saccharide) fingerprints of honey samples.
  • Assess various data processing tools for the treatment of LCMS data
  • Develop a robust end-to-end standard protocol to track quality attributes of honey.
  • Pilot a large-scale inter-laboratory test to assess the performances of the standard protocol.

The Food Toxicant Laboratory (approximately 1,000 square feet) is located in the Macdonald-Stewart building of Macdonald campus of McGill University ( The laboratory is part of the Faculty of Agricultural and Environmental Sciences, one of the eleven faculties of McGill University, is at the forefront in applied bioscience, food, nutritional and environmental sciences research and teaching. The candidate will be provided with research space in this laboratory and the resources to perform his/her research. The Food Toxicant Laboratory is equipped with all the necessary instruments for this project (incl. UHPLC-QTOF-MS/MS, Dionex ASE350, HPLC-DAD…). Research group and individual project meetings are held bi-weekly, alternatively. Research group members are also taking part in events organized in the field of mass spectrometry.

Qualifications:  Please refer to McGill’s requirements on postdoctoral appointments,, for conditions and additional information on the status of the position. (In Quebec, a Postdoctoral Fellow is a full-time student status and trainee category, and the Ministère de l’Education, Enseignement Supérieur et Recherche (MESRS) stipulates that all postdocs must be registered on a university student registration system.) Please note that non-Canadian postdoctoral fellows must have valid Citizenship or an Immigration Canada (CIC) work permit to legally work in Canada. 

Education / Experience: The Food Toxicant Laboratory at McGill University ( is searching for an enthusiastic candidate with a strong interest in food authenticity. The ideal candidate for this position have the following qualifications:

  • A PhD degree in a related field (chemistry, food science, biochemistry, etc.)
  • Strong proven background (published work in peer-reviewed journals) in analytical chemistry, food science, and food analysis.
  • Proficiency in different areas of chromatography, high-resolution mass spectrometry and data analysis.
  • At least two first-authored English papers (or three if co-first authors) with submitted, accepted or published status in peer-reviewed journals
  • Good spoken and written communication skills in English
