The Institute of Radiochemistry and Experimental Molecular Imaging (IREMB) is seeking a postdoctoral researcher for a translational research project in the field of radiopharmaceutical tracer development and molecular imaging. The postdoc position will initially be embedded for one year in the internationally funded IMAGESTRO project. There is an option of extension for another year. The focus of the work will be on the biological validation of newly developed PET or SPECT radiotracers.
The IMAGESTRO project aims to develop novel 18F-labeled PET tracers for the non-invasive imaging of estrogen receptors in the brain, to characterize them preclinically, and to translate them into human applications. The project focuses on the organic synthesis of suitable precursor and reference compounds, the development and optimization
of radiofluorination strategies, and the comprehensive analytical and preclinical characterization of the resulting radiotracers. The work will be carried out in close cooperation between the University Hospital Cologne and Forschungszentrum Jülich and offers an interdisciplinary research environment at the interface of organic chemistry, radiochemistry, radiopharmacy, molecular imaging, biology and neuroscience.
