Bernhard Sattler is the head of the medical physics section of the Dept. of Nuclear Medicine of the University Hospital Leipzig, Germany, and professor of medical engineering. He graduated in electrical and biomedical engineering from the Technical University of Ilmenau, Germany, in 1994 and became a certified medical physicist at the University of Leipzig in 2001. He received his PhD in 2000. He is approved Medical Physics Expert in radiation protection, handling of radionuclides and running a cyclotron. Until he became head of the medical physics section in 2010, he held a senior scientific position. Moreover, he coordinates and runs radiation protection courses for healthcare professionals since 1997. His research interest is in clinical and radiation protection internal dosimetry. In this, his special field of work is the assessment of biodistribution and incorporation dosimetry within preclinical and clinical trials to evaluate new radiopharmaceuticals for PET. For a decade, he is involved in the physical and technical support of the implementation of hybrid cross-modality molecular imaging techniques in interdisciplinary clinical routine and research work-flows. He is immediate past chair and senior adviser of the Physics Committee of the European Association of Nuclear Medicine and Molecular Imaging (EANM) and among numerous other national and international teaching activities an approved expert/lecturer in medical physics in nuclear medicine for the International Atomic Energy Agency (IAEA). He is a full Member of the Editorial Board of the European Journal of Nuclear Medicine Physics and Reviewer for numerous scientific Journals in his field of expertise.
