Stephan G. Nekolla, PhD, FESC, is adjunct professor and the director of medical physics at the Department of Nuclear Medicine at Technische Universität München (Germany). Dr. Nekolla’s research fields are design, acquisition and analysis of PET, SPECT, MRI and CT studies, workflow considerations and quantification methods in clinical and pre-clinical studies. His primary focus is the optimal use of non-invasive imaging to understand the mechanism of disease in cardiology and oncology, their detection and therapy assessment. Especially the use of hybrid devices such as SPECT/CT, PET/CT, and PET/MRI their optimal use in cardiac and oncological imaging is of special relevance. He is the author/co-author of > 260 peer-reviewed publications, book chapters and review articles (Publons H-index: 60, L-1857-2013). Dr. Nekolla is chair of the working group medical physics of the German Society of Nuclear Medicine, ESMIT representative of the physics committee of theEuropean Society of Nuclear Medicine and member of the ESC/EACVI Nuclear Cardiology and Cardiac CT Section. As part of the interdisciplinary imaging network at TU München, he is senior affiliated lecturer at the Chair of Computer Aided Medical Procedures & Augmented Reality (CAMPAR), member of the MunichHeartAlliance as well as member of the German Center of Cardiovascular Research (DZHK). After studying physics at the University of Würzburg, Germany and his diploma thesis at the Institute of Biotechnology, he received his PhD at the Institute of Physics, University of Würzburg, before moving to Munich.
