  • Research interests
    • Geochemistry, mantle geodynamics, noble gas isotopes and the evolution of the Earth: Origin of the Earth, core mantle differentiation, formation of the terrestrial atmosphere, evolution and structure of the Earth's mantle, interaction with the lithosphere
    • Environmental and paleoclimate aspects of noble gas nuclides: Noble gases as tracers of early atmospheric evolution, 39Ar in environmental studies, surface exposure dating using cosmogenic nuclides
    • Isotope chronology: Radiometric dating using radiogenic noble gas nuclides (e.g., 40Ar/39Ar), calibration of age monitor minerals and 40K decay constants
    • Cosmochemistry, planetology and terrestrial planets: Cosmic dust in the interstellar medium and in protoplanetary disks, dust agglomeration, formation of small bodies in the solar system
    • Impacts of asteroids, evolution of planetary surfaces: Radiometric dating of terrestrial impact structures, impact metamorphosed meteorites from asteroids, Mars and the moon
    • Space instruments: Analyses of cosmic dust (CDA/Cassini, COSIMA/ROSETTA, LEOPART), in situ instrument for radiometric dating on planetary surfaces (ISAGE)
  • Methods
    • Mass spectrometry (noble gas isotopes) and standard methods of geochemistry
  • Coordinated research
    • DFG priority programme 1385: "The first 10 million years of the solar system - a planetary materials approach" (coordinator, homepage)
    • DFG research group FOR 759 (deputy speaker)
    • Interstellar dust preliminary examination (ISPE) team of NASA STARDUST mission
    • DFG priority programme ICDP/ODP
  • Teaching
    • Geochemistry of the Earth's mantle
    • Chemistry and origin of the solar system
    • Lectures for astromineralogy, planetary physics, asteroids, comets, meteorites
