Postdoctoral scientist (M/F) Ref° 521

Type of contract: Full-time and determined duration contract (CDD)

The Laboratoire national de santé (Institut public au Grand-Duché de Luxembourg) is recruiting a Postdoctoral scientist in analytical chemistry (PhD in Analytical Chemistry, Biochemistry or a related field) (h/f) for the Unit ‘Environmental Hygiene and Human Biological Monitoring’ (Department Health Protection) in a full time (40h/week), with a fixed-term contract of 24 months (“contrat à durée déterminée CDD”) starting at the earliest convenience.




The LNS is a major player in Luxembourg’s healthcare sector, serving the country’s patients, doctors and hospitals. Under the supervision of the Ministry of Health and Social Security, the LNS is a multidisciplinary public institution organized around six medical departments, two of which are designated as national diagnostic centers for human genetics and pathology respectively. The LNS employs around 400 highly qualified staff with diverse backgrounds. The main purpose of the LNS is to develop analytical activities and scientific expertise relating to the prevention, diagnosis and monitoring of human diseases; to act as a national control or reference laboratory; and to carry out forensic missions. The LNS also collaborates with the University of Luxembourg and other biomedical research institutions, both nationally and internationally, on research and teaching activities. In particular, in the field of diagnostics, the LNS covers the following fields of application: medical biology, microbiology, forensic medicine, environmental medicine, morphological and molecular pathology, and clinical genetics, as well as sequencing for rare diseases, oncology and pathogens.

The Unit ‘Environmental Hygiene and Human Biological Monitoring’ has strong expertise in indoor pollution occupational hygiene and human biomonitoring. The Unit mainly works for the Ministry of Health and is an active partner in the European Partnership for the Assessment of Risks from Chemicals (PARC). PARC is a 7-year science-policy Research &Innovation program that has been launched in May 2022 and that is co-funded by the European Union. . PARC aims to develop next-generation chemical risk assessment to protect human health and the environment and to support the EU Chemical Strategy for Sustainability and the European Green Deal`s “Zero pollution” ambition with new data, knowledge, methods and tools, expertise and networks. The programme involves 200 partners from 28 countries and the EU, including national and EU risk assessment and regulatory agencies as well as affiliated research organisations working in environmental, occupational and/or public health. As national institute, LNS is key partner in several work packages, including human biomonitoring and exposure- and human risk assessment  in the general and in occupational populations.



As a Postdoctoral scientist working in the PARC project, you report directly to the Unit Head. More specifically, you will :

  • Set-up analytical methods for organic pollutants and their metabolites in indoor environmental samples (e.g. air and dust) and in human samples (exposure and effect biomarkers in blood, urine and alternative matrices), by means of GC-MS; GC-MS/MS, GC-QTOF and/or LC-MS/MS;
  • Develop innovative sampling methods in human biomonitoring and occupational hygiene;
  • Draft standard operating procedures (SOPs) and protocols for the developed methods;
  • Validate the developed methods in line with international standards and the quality system (ISO 17025 and ISO 15189);
  • Be in charge of the different phases in risk assessment based on the results of the chemical analyses: data processing, data analyses plans and data analyses, and evaluation;
  • Publish your sampling and analytical methodology developments, validations, risk- and exposure assessments in international peer-review journals;
  • Participate in the different working groups and meetings in PARC related to your tasks, including the QA/QC working groups;
  • Be responsible for the technical reporting in PARC for your tasks and domains you are involved in.

This list of tasks should not be considered exhaustive. Missions may vary depending on the specific needs of PARC / the role of the Unit in PARC.




  • A PhD in chemistry, biochemistry or a related field, with specialization in GC-MS and LC-MS for the analysis of complex organic compounds in environmental and human biological samples;
