Rosalie Nijssen

Rosalie Nijssen is an active Researcher at Wageningen University & Research specializing in analytical toxicology within Team Pesticides 2. Her work focuses on developing advanced methodologies for pesticide detection and risk assessment across food safety, environmental health, and human biomonitoring domains.

Her primary research interests include:

• High-Resolution Mass Spectrometry (HRMS) applications
• Pesticide metabolite identification and quantification
• Food and feed safety control systems
• Biological marker development for exposure assessment
• Veterinary drug analysis in complex matrices

Nijssen's publication record demonstrates consistent innovation in harmonized analytical workflows, particularly for suspect screening of pesticide mixtures. Her recent work emphasizes multi-laboratory validation, European collaborative studies, and novel approaches to uncovering hidden risks in food chains through metabolite tracking and urinary biomonitoring.

As a core member of Team Pesticides 2, she contributes to Wageningen University & Research's leadership in analytical toxicology through method development, inter-laboratory studies, and European regulatory support initiatives focused on pesticide exposure assessment.
