- Provide consulting services to chemical manufacturers, downstream users, and CROs in analytical sciences and regulatory compliance (REACH, CLP, TSCA, ICH).

- Support clients in REACH compliance: dossier preparation and updates, polymer identification, borderline assessments, and monomer threshold calculations.

- Advise on physico-chemical testing strategies for regulatory submissions, collaborating with CROs for study design, monitoring, and reporting.

- Develop and review analytical methods (LC-MS, GC-MS, HPLC, NMR, FT-IR) for extractables & leachables, impurities, and trace-level analyses.

- Review and assess toxicological and physico-chemical study reports for compliance with OECD, ECHA, and ICH guidelines.

- Deliver training and workshops for clients on analytical method development, regulatory data requirements, and best practices in quality/GMP environments.

- Provide strategic advice to clients on regulatory risk assessments, enabling faster market access while ensuring compliance and safety.

Key achievements:

- Guided a mid-size specialty chemicals company in preparing updated REACH dossiers, ensuring full compliance ahead of ECHA deadlines.

- Designed an analytical testing program for extractables in polymeric materials, supporting a medical device manufacturer’s EU market entry.

Management of the analytical group of Huntsman Advanced Materials division in switzerland (Basel). My role was to support the business by providing analytical expertize on different areas as:

• REACH chemical substance registration by providing analytical data interpretation and writing of full analytical reports .

• Product-EHS team support regarding toxicological studies and other product safety topics.

• support Technology & Innovation development teams (R&D) serving areas as Adhesives, E-mobility and New materials.

• Customer technical support (complaints)

• Production plants support (support quality, scale-up, ...)

• Marketing and legal support (patent infringements, ...)

Part of the analytical group, my job consisted to provide analytical support mainly to our REACH and R&D departments. I was responsible for the creation of multi-technique analytical reports for various types of chemical substances (UVCB, polymers, mono and multi-constituents) in order to proceed to the REACH registration of Huntsman products. I, also, provided support to our R&D division, by performing analyses on small and large organic molecules and delivering analytical reports on new development products for different industrial applications (composites, adhesives, coatings, curing agents,..). During this time, I was also supporting Legal department for determination of patent infringements, supporting customer service department and production sites regarding quality purposes. During this time I could deepen my knowledge in analytical sciences, particularly in liquid and gas chromatography techniques as HPLC-MS Ion Trap, HPLC-DAD-ELSD, GPC-RI, GC-FID and GC-MS techniques and in spectrophotometric techniques as UV-VIS, FT-IR, NMR and mass spectrometry.
