Postdoctoral scientist in analytical chemistry (PhD in Analytical Chemistry, Biochemistry or a related field) Ref° 522 (m/f)Le 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) (m/f) the Unit ‘Environmental Hygiene and Human Biological Monitoring’ (Department Health Protection) in a full time (40h/week), with a fixed-term contract of 12 months (“contrat à durée déterminée CDD”) starting at the earliest convenience.About the Laboratoire national de santéThe 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.About the Department of Health Protection and the Service ‘Environmental Hygiene and Human Biological Monitoring’:The Department Health Protection supports public health and health care for problems caused or aggravated by the environment, including indoor pollution, the working context, and consumer products. We fulfill this mission through servicing including expert advice, education and applied research. Our main stakeholders are the hospitals, the ministries and the services for occupational medicine in Luxembourg.The Department Health Protection hosts two Services:

• The Service “Environmental Hygiene and Human Biological Monitoring” carries out laboratory analyses – chemical and microbiological – in dust, air and surface samples (ISO/IEC 17025 accreditation). In parallel, the Service analyses the concentrations of substances or their metabolites directly in human medical samples, for example blood, urine, hair. The Service measures not only human biomarkers of exposure (ISO 15189 and ISO/IEC 17025 accreditation), but is expanding its portfolio of human biomarkers of effect relevant in the pathways of disease development and progression.

The Service is also an active partner in the European Partnership for the Assessment of Risks from Chemicals (PARC). PARC is funded by the European Union’s “Horizon Europe” framework program for the period of 2021-2027. Within PARC, LNS is grant signatory for Luxembourg and key partner in several workpackages related to human biomonitoring and risk assessment for human exposure to chemicals from the indoor and occupational environment. It involves 200 partners from 28 European countries, including national and EU agencies as well as affiliated research organizations.

• The Service “Medical Expertise and Data Intelligence” hosts the medical, epidemiological and toxicological expertise in environmental and occupational health/medicine. The Service supports the National Service for Environmental Medicine at the Hospital Center Emile Mayrisch (CHEM) and is in charge of the European science-policy programs and the epidemiological surveys in the general and working population in Luxembourg that include human biological monitoring and/or environmental/occupational exposure assessment.

A departmental administrative team and a departmental quality and technical coordination team support the Services and the department head.Job descriptionAs a Postdoctoral scientist working in the PARC program, you report directly to the Head of Service. More specifically, you will:

• Set-up analytical methods for organic pollutants and their metabolites (exposure and effect biomarkers) in human samples (blood, urine and alternative matrices) and in indoor environmental samples (e.g. air and dust) 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 the department’s quality system and international standards (ISO/IEC 17025 and ISO 15189);
• Publish your analytical methodology developments and validations in international peer-review journals;
• Habilitate and support laboratory technicians;
• Participate in the daily maintenances and problem solving related to the analytical instruments (GC-MS; GC-MS/MS, GC-QTOF and/or LC-MS/MS);
• Active involvement in other PARC tasks, e.g participation in meetings, workshops and technical reporting.

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

• A PhD in chemistry, biochemistry or a related field, with specialization in GC-MS, GC-MS/MS and LC-MS/MS for the analysis of complex organic compounds in environmental and human biological samples;
• Experience in human biological monitoring and/or chemical analyses in environmental matrices (dust, air)
• Experience in the method development of organic compounds in a chemical laboratory, preferentially in the field of environmental and occupational health;
• Track-record of valorization of your work, via peer-review publications and presentations at congresses ;
• A perfect fluency in English and/or French (oral and written).

Will be considered as an asset:

• Knowledge of other analytical techniques (e.g. ICP-MS);
• Working experience in an accredited chemical laboratory according to the ISO/IEC 17025 or 15189;
• Statistical analysis skills ;
• Working proficiency in Luxembourgish and German.

Key skills

• Strong organizational skills and structured way of working;
• Strong analytical thinking;
• Excellent team working and networking skills;
• Strong writing skills for technical reports as well as for international peer-review scientific journals;
