Jouw functie

The 4-year Ph D program focuses on developing rapid screening methods using high-resolution mass spectrometry (HR-MS) to detect chemicals in consumer articles and identify toxic substances through effect-directed analysis (EDA).
The Ph D research will be embedded in the European Partnership for the Assessment of Risks from Chemicals (PARC). PARC’s mission is to address chemical safety challenges by developing next-generation risk assessment, supporting the European Green Deal's goal of a toxic-free environment.
The enforcement of EU chemical safety legislation is crucial for advancing the European Green Deal agenda and the Chemicals Strategy for Sustainability. Effective enforcement ensures EU citizens are protected from regulated substances and maintains fair competition among producers and importers. Advances in analytical techniques and chemical information systems offer new opportunities to identify chemicals of emerging concern. However, these novel methods are underutilized in regulatory contexts. This project aims to evaluate and develop rapid screening methods for identifying priority substances across various sample matrices. These methods will enhance enforcement actions, supporting national authorities in implementing key regulations like REACH, CLP, and product-specific legislation such as the Ro HS Directive and regulations on food contact materials.
The candidate will develop high-resolution mass spectrometry (HR-MS) suspect and non-target (SNTS) workflows tailored to rapidly identify regulated and emerging chemicals of concern in consumer articles. This will require a strategic approach that integrates existing HR-MS and ambient MS techniques. The goal is to create a methodology suitable for the enforcement of chemical legislation, contributing to better consumer protection and regulatory compliance.
In the second stage of the project, effect-directed analysis (EDA) will be used to prioritize the identification of additives and other chemicals of emerging concern in consumer products and other (environmental) samples. The findings will be published in peer-reviewed scientific journals. These publications will form the basis of the Ph D thesis.
Your duties

• Developing fast screening HR-MS methods using ambient MS techniques to support the enforcement of chemicals in consumer articles
• Use of hyphenated techniques such as LC-QTOF-MS, (tims)-QTOF-MS, GC-HR-MS, DART-QTOF-MS etc.
• Setup comprehensive SNTS workflows for the prioritization and annotation and semi-quantification of regulated and emerging chemicals.
• Active participation in PARC.
• Effect-directed analysis methodologies including high resolution fractionation, and different in vitro bioassays for screening.

Further duties and expectations

• Ensure and report quality assurance/control (QA/QC) of the produced data
• Supervision of Master’s students in their research and literature theses within the framework of the project.
• Involvement in teaching, e.g. supervision of working groups or practicals at BSc and MSc level.
• Dissemination of results in peer-reviewed journals and at (inter)national conferences
• Write and defend a Ph D thesis at the VUA.

Jouw profiel

• Required diploma: MSc in analytical chemistry, or an equivalent degree in a closely related field.
• Expertise: analytical chemistry (e.g. liquid and/or gas chromatography, high-resolution mass spectrometry), suspect/nontarget screening workflows, excellent command of the English language, and scientific writing skills.
• Affinity with toxicology / in vitro bioassays
• Strong analytical problem-solving skills and attention to detail.
• A team player but is also able to work independently.

Over ons

A-LIFE
The department Amsterdam Institute for Life and Environment (A-LIFE) brings together the former departments of Environment & Health, Molecular Cell Biology and Ecological Sciences. A-LIFE seeks to connect properties and emerging behaviours across all scales, from molecules to ecosystems, including human populations. The section Chemistry for Environment and Health investigates environmental and human exposure, focusing on the development and application of advanced analytical methods for accurate, robust exposure of the assessment to a wide variety of chemicals.
Faculty of Science
Researchers and students at VU Amsterdam’s Faculty of Science tackle fundamental and complex scientific problems to help pave the way for a sustainable and healthy future. From forest fires to big data, from obesity to malnutrition, and from molecules to the moon: we cover the full spectrum of the natural sciences. Our teaching and research have a strong experimentally technical, computational and interdisciplinary nature.
We work on new solutions guided by value-driven, interdisciplinary methodologies. We are committed to research, valorisation and training socially engaged citizens of the world who will make valuable contributions to a sustainable, healthy future.
