PD Dr. Johannes Notni

Johannes Notni studied chemistry at the Friedrich-Schiller-Universität in Jena. During his diploma and PhD thesis at the Institute for Organic Chemistry and Macromolecular Chemistry, he focused on the mode of action of zinc enzymes and obtained a doctor's degree for a thesis about "Zinc thiolate and hydrosulfide complexes as versatile enzyme models". In 2007 and 2008, he went to the Group of Coordination and Bioinorganic Chemistry at Charles University in Prague, funded by a postdoc grant from the German Academic Exchange Service (DAAD), where he initiated a research programme on innovative 68GaIII-chelators for application in positron emission tomography. In 2009, he continued these activities at TUM and expanded his research interests to radiometal complexes for nuclear imaging and therapy, MRI contrast agents, as well as preclinical evaluation and clinical translation of innovative radiopharmaceuticals. He teaches at the radiopharmacy and inorganic chemistry departments and finished habilitation in 2015.

For his research, he received several awards, among them the "Radiopharmaceutical Council Young Investigator Award, 1st Prize" of the Society of Nuclear Medicine (2011) and the Innovation Prize in Medicinal and Pharmaceutical Chemistry awarded by the Gesellschaft Deutscher Chemiker (GdCh) and Deutsche Pharmazeutische Gesellschaft (DPhG) (2013). In 2016, he received the EANM Springer Prize for the most cited paper in EJNMMI Research, and in 2017, the Georg von Hevesy Prize from the Deutsche Gesellschaft für Nuklearmedizin (DGN).

Johannes Notni is leader of the research project A10, "Targeting α5β1 integrin for imaging of tumor angiogenesis and antiangiogenic therapy", in the framework of the Collaborative Research Centre 824, "Imaging for Selection, Monitoring and Individualization of Cancer Therapies".

During his 15-year teaching career, he has held lab courses, seminars, and lectures in basic organic and inorganic chemistry, radiochemistry, and radiopharmacy, and supervised lab courses in inorganic and analytical chemistry at TUM. Currently, he regularly teaches radiopharmacy at the TUM faculties of medicine and chemistry.
