Research interests

Main topics of my research are the dosimetry, dose calculation, outcome assessment and quality assurance in radiation oncology as well as the implementation and evaluation of novel treatment techniques. This includes adaptive treatment strategies where changes in patient anatomy over the course of the treatment are compensated. Implementation of these strategies require a rigorous quality assurance process to ensure patient safety. In the field of dosimetry, my main focus is accurate determination of absorbed dose in small and non-standard radiation fields. Detailed knowledge of physical phenomena in these fields as well specific detector characteristics will improve the accuracy of the radiation dose delivered to the patient.
