    My field of research is Accelerator Mass Spectrometry using gaseous carbon-dioxide samples. Using a combination of an Elemental Analyzer, an Isotope Ratio Mass Spectrometer and a gas system I am pushing the limits for ultra-sensitive carbon-14 dating.

    I am working on medical applications of nuclear physics. My Ph.D. project is creating a silicon tracker detector in collaboration with GSI Darmstadt. The detector will be used in cancer radiation therapy with heavy ions to better determine where the treatment beam is located in the patient during treatment.

    My interest lies in nuclear astrophysics. Using the AMS facilities I am researching the possibility to measure neutron capture rates of unstable nuclei, which is important to better understand the origin of elements in the universe.

    I have completed my Masters degree setting up a low-energy AMS system for the detection of tritium in reactor graphite samples. In my Ph.D. thesis I will continue exploring the possibilities of tritium detection and are also developing a high-performance particle detector for the 10MV AMS setup.

    I am the project leader of the new ALIS setup, a laser and ion cooler device for the suppression of isobars in AMS. I am supervising the students working on this interesting new project. In the past years I have developed numerous devices and setups at both the 6MV and 10MV AMS systems.

    I am developing the AMS measurement for the Iodine-129 isotope. The results will improve our understanding of how plants grow in the Atacama desert, one of the most dry places on earth. This topic is part of the CRC1211 collaborative research centre.

    The topic of my Bachelor thesis is improving the sensitivity of Accelerator Mass Spectrometry using gaseous carbon dioxide samples for enhanced carbon-14 dating. I have found an improved way to prepare our samples to guaranty much more stable measurement results.

    My Ph.D. work is on the isotope Sr-90, a hazardous isotope for humans and the environment. Using the 10MV Accelerator Mass Spectrometry setup I am able to detect very small amounts of this isotope. The results are important for a safe decommissioning of nuclear facilities.
