GC–MS PostDoc positions and fellowships

The University of Antwerp seeks a full-time postdoctoral researcher to develop and optimize analytical platforms for metabolomics and lipidomics in human biological fluids, supporting exposome studies. The role involves refining LC-QTOF-MS and GC-QTOF-MS methods, developing targeted LC-MS/MS and GC-MS/MS assays, implementing QA/QC workflows, and supervising graduate students. Candidates should hold a PhD in analytical chemistry or related fields, with hands-on experience in HRMS, bioinformatics, and peer‑reviewed publications.

The University of Antwerp seeks a motivated postdoctoral researcher to develop and optimize analytical platforms for untargeted and targeted metabolomics and lipidomics in human biological fluids such as blood and urine. The project involves refining LC-QTOF-MS and GC-QTOF-MS methods, implementing additional separation dimensions like 2D-LC or ion mobility, and improving data processing workflows for accurate metabolite annotation. The successful candidate will contribute to exposome studies, validate biomarkers for clinical conditions, and publish results in peer‑reviewed journals while supervising master and PhD students.

The Jožef Stefan Institute invites applications for a Postdoctoral Researcher position within the Department of Environmental Sciences, focusing on food chemistry and environmental analysis. The successful candidate will conduct independent and team-based research on volatile organic compounds, stable isotopes of light elements, and bioactive compounds in food and environmental samples. Responsibilities include processing, interpreting, and statistically analyzing experimental data, preparing research projects and reports, publishing scientific papers, presenting results at national and international conferences, and mentoring students. The role requires a PhD in food science, chemistry, biochemistry, nutrition, biology, or a related field, along with hands‑on experience in laboratory work, proficiency in instrumental techniques such as GC‑MS, LC‑MS, IRMS, and data analysis tools like R, and strong English communication skills. The appointment is for a fixed term of two years, with possible extension, and includes a three‑month probationary period, salary according to the Slovenian public sector pay system, and access to modern research infrastructure.

The POSTDOCTORAL RESEARCH SCHOLARSHIP under the SHIELD‑HMP project invites candidates with a recent PhD in chemistry, pharmaceutical sciences, pharmacology and toxicology, chemical and biological engineering, or environmental engineering to work on the prevention and mitigation of health risks posed by hazardous medicinal products. Based at the Institute of Public Health, University of Porto, the scholar will conduct hazard identification, exposure assessment, early biological effect and cancer risk evaluation, and cleaning protocol effectiveness studies under the supervision of Mónica Santos. The position offers a monthly maintenance allowance of €1,901.00, a 12‑month contract (renewable), and access to advanced analytical facilities for micropollutant analysis using LC‑MS, GC‑MS, and various extraction techniques.

This PhD position investigates how gut microbiota mediate colonization resistance against pathogens using *C. elegans* models. The student will identify microbial species and metabolites inhibiting pathogens like *Salmonella* via proteomics and mass spectrometry, while exploring host immune interactions. Training includes microbiome analysis, advanced analytical techniques, and scientific writing.

The University of Iowa’s IIHR–Hydroscience and Engineering and the Center for Health Effects of Environmental Contamination (CHEEC) are seeking multiple postdoctoral research scholars to contribute to the Iowa Integrated Network for Science, Information, and Geospatial Health Tracking (Iowa INSIGHT). This initiative investigates how environmental exposures affect human health across Iowa, focusing on cancer rates, maternal and newborn health, reproductive health, and neurodevelopmental disorders. Scholars will work on environmental monitoring and biomonitoring using LC‑MS/MS and GC‑MS/MS techniques, process water, air, soil, and biospecimen samples, and communicate findings to the public. The position is full‑time for one year with possible renewal, supported by the Kyle J. and Sharon Krause Family Foundation.

This postdoctoral associate position at Cornell University’s Department of Horticulture focuses on developing and evaluating non‑neonicotinoid seed‑applied protection strategies for early‑season pests in New York cropping systems. The role involves laboratory, greenhouse, controlled‑environment, and field experiments, seed coating formulation, data analysis, manuscript preparation, mentoring of undergraduate assistants, and stakeholder engagement. A Ph.D. in a related field is required, and the position offers an annual salary of $63,480.

The position offers a 24‑month post‑doctoral fellowship at LIST in Luxembourg to develop advanced molecular analysis and imaging strategies for rubber composites. The researcher will work within a Goodyear‑LIST partnership, using mass spectrometry imaging, NMR, and chromatography to study additives in complex polymer matrices, publish in Q1 journals, and present at international conferences.

This postdoctoral fellowship at the University of Antwerp’s Toxicological Centre focuses on assessing human exposure to PFAS and PFAS‑free alternatives in healthcare products. The researcher will develop and apply advanced LC‑HRMS and GC‑HRMS methods, conduct leachables/extractables analysis, model exposure scenarios, and contribute to risk assessment and substitution strategies within the EU HORIZON‑IHI PFAROS project, while supervising students and disseminating results.
