Short Biographical Sketch

Willi A. Kalender received his Master`s Degree and Ph.D. in Medical Physics from the University of Wisconsin, Madison, Wisconsin, USA in 1979. In 1988 he completed all postdoctoral lecturing qualifications (Habilitation) for Medical Physics at the University of Tübingen.

From 1979 to 1995 he worked in the research laboratories of Siemens Medical Systems in Erlangen, Germany, from 1988 to 1995 as head of the department of Medical Physics. Since 1992 he has been Visiting Professor of Medical Physics at the University of Wisconsin. In 1995 he was appointed full professor and director of the newly established Institute of Medical Physics at the Friedrich-Alexander-University Erlangen-Nürnberg, Germany. In 1999 he became Distinguished Visiting Professor to the Department of Radiology at Stanford University, Stanford, CA, USA. Willi A. Kalender has conducted research mainly in the area of diagnostic imaging. The development and introduction of volumetric spiral computed tomography was a particular focus of his work. Other highly interesting fields of research were radiation protection and the development of quantitative diagnostic procedures, e.g. for the assessment of osteoporosis, lung and cardiac diseases. His work is documented in more than 880 scientific papers, more than 300 original publications among these, and more than 30 patents.

Willi A. Kalender is a Fellow of the American Association of Physicists in Medicine; from 2005 to 2007 he was Member-at-large of the Board of Directors of this society. From 1997 to 2008 he was member of the International Commission on Radiation Units and Measurement (ICRU). Since 2009 he is an elected member of the German Academy of Sciences Leopoldina. In 2009 and 2011 he was awarded honorary doctorates in Medicine by the Medical School of the RWTH Aachen, Germany, and the Medical School of the University of Zurich, Switzerland. He organized and hosted numerous international workshops and conferences, among them the World Conference of Medical Physics in 2005 in Nuremberg, Germany.
