Postdoctoral scientist in chemical risk assessment (H/F) Ref°522

TYPE DE CONTRAT : CDD - temps plein

Le Laboratoire national de santé(Institut public au Grand-Duché de Luxembourg) is recruiting Postdoctoral scientist in chemical risk assessment for the Unit ‘Medical Expertise and Data Intelligence(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.

About the Laboratoire national de santé (LNS) and the Department Health Protection:

The « Laboratoire national de santé » (LNS) is a public institution under the supervision of the Ministry of Health in Luxembourg. Organised as a multidisciplinary institute and supported by a professional services team, the LNS includes four scientific departments in the fields of medical biology, microbiology, forensic medicine and health protection, in addition to hosting the National Center of Pathology and the National Center of Genetics. The LNS has its premises in Dudelange, with state of the art, modern infrastructure in line with recent developments in medical sciences. Its objective is to develop scientific and analytical expertise related to the prevention, diagnosis and monitoring of human diseases. Its ultimate mission is to serve patients and citizens and offer excellence in health care.

The Department of Health Protection supports public health and health care for problems caused or aggravated by environmental pollution, including the indoor environment, the working context, consumer products, food and food contact materials. We fulfill this mission through servicing, expert advice and applied research. Historically, the Department consisted of two units that are in charge of the laboratory analyses in human food and in environmental and occupational health, respectively. In, 2021, the Department has initiated the setting up of a third Unit Medical Expertise and Data Intelligence (MEDI). The new Unit hosts the epidemiological, toxicological and medical expertise in the fields of environmental and occupational health.

The Department of Health Protection 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 programme 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 and involved in human biomonitoring, exposure and risk assessment projects (general and occupational population context).

The Departments` senior experts in the specific domains of toxicology, exposure science and human health risk assessment are actively involved in international and European experts groups and committees, such as the ECHA Risk Assessment Committee, OECD working groups and projects, in scientific societies, such as ISES. The Department` expertise thus is internationally recognized and well connected to follow the latest state-of-the-art in the expert domain of exposure assessment, risk assessment and the regulatory arena.

Job description

As an expert in exposure and human health risk assessment and working in the PARC project, you report directly to the Senior Project Manager Environmental Health and Risk Assessment with a PhD in Toxicology and more than 15 years of experience in risk assessment. More specifically, you will:

  • Contribute to dedicated PARC projects on source-to-dose and aggregated exposure assessment aiming to develop a strategy and model toolbox for aggregated exposure assessment for the regulatory context;
  • Analyze human biomonitoring and indoor exposure data for its suitability for evaluation and further development of exposure models;
  • Conduct risk assessments based human biomonitoring data; process analytical results and perform human health risk assessment tasks, including the chemical analytical data evaluation, exposure assessment, and human health risk assessment;
  • Use advanced human health exposure and risk assessment models, such as MCRA (Monte Carlo Risk Assessment);
  • Participate and co-lead PARC working groups and case studies on indoor and occupational exposure;
