Johannes Petzoldt studied Physics at the Technische Universität Dresden, Germany. He obtained his Diploma in March 2013, with a project on neutron and proton activation of natural neodymium for the SNO+ experiment.
Until September 2016, he worked as an assistant researcher on the topic "range verification for proton therapy" at OncoRay in Dresden, Germany. Johannes investigated scintillation materials as well as the beam characteristics at the proton therapy facility with respect to the novel Prompt Gamma Timing (PGT) method. Furthermore, he tested and characterized a PGT prototype system for the application in clinical practice.
Johannes joined the OMA project to work at Ion Beam Applications (IBA) in Louvain-La-Neuve, Belgium. There, he will continue his research on range verification based on prompt gamma rays. The focus is set on the further clinical implementation of the prototype of the knife-edge slit camera. The aim is to improve the clinical workflow and to develop routines for determining the causes of range shifts during the treatment based on measurements by the slit camera.
