Patrick Bäuerlein is a chemical researcher in the Chemical Water Quality and Health team, and his main field of expertise is the chemical quality of the entire water cycle. He works predominantly on the detection and removal of contaminants. Patrick is particularly interested in nanoparticles, microplastics, passive sampling, water treatment and new analytical methods for monitoring and detecting organic micro-pollution in water. He has experience with techniques such as field flow fractionation, TGA-GC/MS, mass spectrometry and infrared imaging techniques to analyse particles (mainly plastics). In recent years Patrick has worked on several large national and international projects, such as NanoNextNL, TAPES, Aquarius, TRAMP and Solutions. Patrick read chemistry at the RWTH Aachen in Germany. He then started working on his PhD research at Eindhoven University of Technology and the University of York in the United Kingdom. During his studies and time as a PhD student he gained experience in the field of analytical, organic and technical chemistry. Besides his research activities, Patrick is also a member of the LLN-ta (national laboratory network of terrorist attacks), the RGEN (Radiological and Health Expertise Network), and attends expert meetings of RIWA and IAWR.
