Position: Postdoctoral Position on Non-invasive Monitoring of Ion-beam Therapy based on Secondary-Ion Tracking

Department: Medical Physics in Radiation Oncology

Code number: 2019-0343

The German Cancer Research Center is the largest biomedical research institution in Germany. With approximately 3,000 employees, we operate an extensive scientific program in the field of cancer research.

Job description:

We are looking for a postdoctoral researcher to work on the optimization of the method of secondary-ion tracking for monitoring of the ion-beam therapy. This position is part of the proof-of-concept trial “In-vivo monitoring of carbon-ion radiotherapy delivery” aiming at optimizing the method for clinical application in daily routine. The main task will be the further development of the secondary-ion detection system that is going to be used in the clinical trial. The detection system is based on multiple silicon pixel detectors (Timepix3 detectors). Its design in terms of detector positions and dimensions around the patient’s head will be optimized. The optimization will be based on dedicated experiments with patient models, Monte Carlo simulations and recommendations of the clinical personnel at the Heidelberg Ion-Beam Therapy Center (HIT).

The project is funded for three years. The initial contract is limited to one year. After the positive decision of the Ethics Committee, the position will be prolonged by at least two years.   ​


We are looking for a highly motivated postdoctoral researcher, preferably with a strong background in the field of ion-beam therapy and experiences with radiation detectors.

The successful candidate should ideally have the following qualifications:

  • PhD in physics, medical physics or closely related discipline
  • Experience with experimental work involving radiation measurements, ideally experiences with detectors capable of single-particle detection
  • Strong skills in the development of algorithms/scientific programming in Matlab, C++, Python or similar; these skills are required for the evaluation of the data measured with silicon pixel detectors
  • Good teamwork & communication skills in order to facilitate productive teamwork with colleagues comprising Master/PhD students, postdocs and engineers at DKFZ and clinical personnel at HIT
  • Experiences with Monte Carlo codes (FLUKA or Geant4) are an advantage
  • Good level in written/spoken English
  • Scientific records will be considered in the evaluation

We offer:

  • Interesting, versatile workplace
  • International, attractive working environment
  • Campus with modern state-of-the-art infrastructure
  • Salary according to TV-L including social benefits
  • Possibility to work part-time
  • Flexible working hours
  • Comprehensive further training program
  • Access to the DKFZ  International Postdoc Program

Earliest possible start date: as soon as possible

Duration: The position is limited to 1 year with the possibility of prolongation.

The position can in principle be part-time.

Application deadline: 13.12.2019
