The Hazard Assessment Directorate takes care of substance evaluation, dossier evaluation, harmonised classification and labelling, occupational exposure limits and listing substances for Candidate and Authorisation Lists. Across four Units, working in close cooperation, we ensure that the Agency is well prepared to carry out these activities by utilising the best possible scientific, technical and regulatory capacity and working in an efficient and transparent way. The Units also provide scientific and technical input to helpdesk activities, and to the development of guidance documents and scientific IT tools, within the scope of their competence. In this professional and challenging setting we have opening for trainees with analytical skills and pro-active attitudes.
Assignment
We are looking for trainees who will be working in L1 – L4 Units on various scientific projects covering the competences listed. In these traineeships you will have the unique possibility to work with tasks related to the regulatory tasks carried out in this Directorate. In this role you will support the Hazard Assessment Units in their daily activities and also contribute to project work related to further investigation and analysis of the data submitted in REACH registrations and CLH dossiers. We are looking for candidates with either an Environmental profile (e.g. background in environmental sciences, ecotoxicology) or a Human health profile (e.g. toxicology, biomedical, pharmaceutical, life sciences). Candidates are invited to choose between one of these two options when applying. In case candidates wish to apply for both profiles, it is necessary to submit a separate well-founded application for each profile.
The tasks may include:
1. Contribution to the analysis of literature data and experimental studies and investigate how substances affect the following endpoints Environmental profile:
o aquatic toxicity
o ecotoxicology
o PBT/PMT assessments
o environmental endocrine disruption
o nanomaterials
o endocrine disruption
Human health profile:
o mutagenicity/carcinogenicity
o reproductive toxicicity
o neuro- and immunotoxicology
o epidemiology
o nanomaterials o endocrine disruption
If you are interested in specific projects listed below please indicate and motivate it in your application.
Future trainees in units L1-L4 may work e.g. on projects related to:
• Curation of adsorption/desorption data and model predictive performance. Potential analysi of simulation data to extrapolate results of one study to other compartments.
• Support in identification of well characterised substances to be used to assess endocrine activity.
Profile
• Completed university degree in a science field related to the area of the REACH regulation:
o Environmental profile (Chemistry, Biochemistry, Ecotoxicology, Environmental Sciences, etc.);
o Human health profile (Toxicology, biomedical, pharmaceutical, life sciences)
• Good analytical skills;
• Proactive attitude;
• An eye for detail;
• Goal-orientation;
• Good communication and interpersonal skills;
• Aptitude for team work;
• Good English skills both written and spoken (as this is the working language of the Agency).
