Postdoctoral research fellow in the field of Positron Emission Tomography (PET) radiochemistry to perform research in the areas of radiochemistry methodology, radiopharmaceutical development, and PET imaging. Successful candidates will join a multi-disciplinary team of chemists, physicians, physicists and biologists in the University of Michigan Medical School, investigating new methods of radiolabeling small molecules for the in vivo imaging of human biochemistry. A Ph.D in organic or medicinal chemistry and the ability to perform multi-step organic syntheses and characterize products are a must. Excellent written and communication skills are also essential. Additional experience with artificial intelligence, machine learning, coding, cGMP, HPLC, micro-scale reactions, fluorine chemistry, radiochemistry preclinical PET imaging are considered a plus, but not essential, as extensive training will be provided. Some background in biology, biochemistry or pharmacology would also be beneficial. Responsibilities will include: synthesis of bioactive molecules and radiochemistry precursors; labeling with carbon-11, fluorine-18, gallium-68, copper-64 radionuclides; optimization of reactions, including with machine learning, purification, characterization and formulation of radiotracers for clinical and pre-clinical research collaborations in neurology and oncology.
