Professor Caldwell completed his PhD at the University of Wisconsin in 1987. He spent the following 15 years at Columbia University primarily pursuing research into proton structure and related topics. In 2002 he joined the Max Planck Institute for Physics as a director. Since 2004 he has been involved in the search for neutrinoless double beta decay. His current accelerator research activities focus on plasma wakefield acceleration. AWAKE, a demonstration experiment, is under preparation in CERN. Professor Caldwell also takes a keen interested in probability, statistics and data analysis techniques and teaches these subjects at TUM. He has been managing director of the Max Planck Institute for Physics since April 2012.
