Updated: 10 days ago
Deadline: ;

The Marie Skłodowska-Curie European Training Network (ETN)  REVAMP, is looking for four highly motivated and talented students with an MSc degree who are interested in an European Industrial Doctorate (EID) within an ambitious multidisciplinary project on reference materials for the environmental contaminants chlorinated paraffins (CPs) and perfluorinated alkyl compounds (PFAS)

Job description
REVAMP Project’s overall goals

The recent United Nations Global Chemicals Outlook II predicts a doubling of the volume of the global chemicals market within ten years. The impact of new emerging chemicals on humans and the environment remains largely unknown. Therefore, it is necessary to improve the capacity of the chemical metrology sector to identify and quantify exposure to new chemical pollutants. The EU-funded REVAMP (Reference materials and validated methods for emerging pollutants) project will offer innovative training to four early-stage researchers (ESRs). It aims for scalable solutions to rapidly identify, develop, produce and implement new certified reference materials and methods for the assessment of new and existing chemical compounds, in particular chlorinated paraffins (CPs) and perfluorinated alkyl compounds (PFAS). The ESRs will combine scientific research and business experience to solve specific challenges at the interface of organic and analytical chemistry, and toxicology relevant to the chemical metrology sector.

The four ESRs described here will be hosted by the Vrije Universiteit Amsterdam (VUA). Their ambitious mandate is to synthesize and certify analytical standards of high purity to enable a reliable analysis of CPs and PFAS in environmental matrices.

REVAMP training is implemented via close collaboration of leading organisations and includes a mobility plan based of secondments of ESRs between the academic and non-academic partners. During the 3-year doctorate study, each ESR will spend 18 months at the Vrije Universiteit Amsterdam, 14 months at the  industrial partner CHIRON (Trondheim, Norway) and 4 months on secondments at two non-academic partner organisations, i.e. the European Reference Laboratory, Freiburg (Germany), the Marine Institute, Galway (Ireland), Bruker, Bremen (Germany) or Waters, Manchester (UK).

The ESRs will team up combining academic research, business and industrial knowledge to overcome specific challenges related to the chemical metrology cycle, including: i) screening and identification of target CPs and PFAS for which analytical standards are needed, ii) synthesis of analytical standards for CPs and PFAS, iii) developing, validating, and implementing analytical methods to measure CPs and PFAS in various matrices, iv) investigating (bio)transformation pathways and conduct in-vitro toxicity testing.

Two of the ESRs will focus on the CPs and two on PFAS. In addition, two of the ESRs will use biological in vitro methods (biotransformation/bioassays). Depending on your interest and experience, we therefore recommend to indicate your preference for one or more of the PhD positions in your application.

Your duties

The main researchs topics of the four PhDs

PhD 1

  • Synthesis of individual CP congeners and mixtures with a focus on long-chain (LC) CPs, CPs comprising other halogens, and 13C labelled standards
  • Development, validation, and implementation of analytical methods for the determination of CPs in environmental matrices, feed, and food
  • Use of hyphenated techniques such as LC-APCI-QTOF-MS, GCxGC-µECD or -MS, LCxLC-QTOF-MS, GC-ECNI-MS, (tims)-QTOF-MS
PhD 2
  • Screening, identification, synthesis and preparative purification of most relevant CP biotransformation products, de-chlorination (olefins), oxidation products and individual CP congeners with a focus on synthesis of larger amounts for toxicity test purposes
  • Investigate (bio)transformation pathways and conduct in vitro toxicity testing
  • Develop analytical methods for the determination of CP biotransformation products
PhD 3
  • Screening of emerging PFAS, like possible transformation products of side-chain fluorinated polymers used in the durable water chemistry, firefighting foams, and the indoor environment using high-resolution MS
  • Develop new methods for the synthesis of these emerging PFAS including 13C labelled analytical standards
  • Development, validation, and implementation of analytical methods for the determination of the newly identified and synthesized PFASs compounds together with the already known PFAS
PhD 4
  • Determine the putative identity of bioactive PFAS found in the environment by Effect-Directed Analysis, combining high resolution fractionation, in vitro toxicity testing and high resolution MS
  • Synthesize these emerging PFAS for analytical and toxicological purposes with extra attention to making larger amounts available for toxicity tests, and chemical purity of the reference materials, which is needed to perform proper toxicity studies)
  • Confirm the identity and toxicity of the synthesized PFAS
Further duties and our expectations
  • Inter/transdisciplinary collaboration in the ESR team
  • Ensure QA/QC of data produced
  • Supervision of Master’s students in their research and literature theses within the framework of the REVAMP project
  • Regular progress updates at REVAMP project meetings and group meetings
  • Dissemination of results in peer-reviewed journals and at (inter)national conferences
  • Write and defend a PhD thesis at the VUA

  • Required diploma: MSc in organic, pharmaceutical or analytical chemistry, or an equivalent degree in a closely related field
  • Required expertise: Organic chemistry, analytical chemistry (e.g. liquid and/or gas chromatography, mass spectrometry), excellent command of the English language and scientific writing skills
  • Recommended expertise: In vitro bioassays (PhDs 2 and 4)
