Department:
Solar System, Impacts and Meteorites

I am part of the management team of the research area FB1 "Dynamics of Nature" and head the Solar System, Impacts and Meteorites department.

I am researching the role of impact processes in the evolutionary history of our solar system Using computer simulations and impact experiments in the laboratory: 

- Collisions of planetesimals and planetary embryos during the main accretion phase of the planets 

- Formation of the moon by collision of the protests with a Mars-sized planetary body 

- Late accretion of planets and its influence on the development of habitable conditions on Earth 

- Mass extinction events caused by asteroid impacts, e.g. Chicxulub impact and the extinction of the dinosaurs. 

- Effects of future impacts on the environment - Planetary defense, deflection of asteroids by a kinetic impactor

Project(s)

  • Third-Party Funded Project

    Deflecting dangerous asteroids

    Providing scientific evidence for the possibility of deflecting an asteroid by external bombardment

  • Third-Party Funded Project

    Effects of meteorite impacts

    Developing a database composed of simple estimates and a large number of pre-processed simulations of probable impact scenarios

  • Third-Party Funded Project

    Late Accretion onto Terrestrial Planets

    The project investigates Earth's evolution after the Moon's formation, from magma ocean to habitable planet, using impact research and numerical modelling.

  • Third-Party Funded Project

    MEMIN - Experimental Impact Research

    The MEMIN network investigates impact processes through interdisciplinary lab experiments with light-gas guns and numerical modelling of impact craters.
