You will work as an independent researcher in a team focusing on the development and application of field flow fraction (FFF) techniques for nanoparticles analyses with a focus on nanoplastics (environmental and biological matrices). Developing tools for the analysis of nanosized plastics and studying their interactions with other (macro)molecules by asymmetrical-FFF (AF4) will be your main objective. Mass spectrometry will be used for identification and quantitation purposes. You will work within a team of scientists to conduct both collaborative research in addition to your own research to develop both sample preparation and separation methods. As a team member you will propose and carry out new developments that improve the analytical capacity of our research. In addition to your research, you will be expected to train and teach internal and external researchers (students, trainees and collaborators) in the use of our AF4, MS and allied methods and participate in research discussions, including own research involvement.
