My own research
My research is currently focused on the role that bolide impact events have had in the evolution of the Earth and other inner Solar System bodies.
Impact events were a lot more common on the early Earth than they are today. However, understanding the precise role of impact cratering in Earth’s early evolution is complicated by the lack of early crust preserved in the geological record. One aspect of my research is therefore to understand what the detrital mineral record can tell us about impact cratering during Earth’s very early development.
A second branch of my research is impact chronology. Impact cratering events can only be correlated with other geological events, such as mass extinctions, when they are very well dated. However, only ca. 10 % of the ca. 190 confirmed impact craters on Earth are considered to be accurately and precisely age dated. Dating of shocked minerals, such as zircon, allows us to date terrestrial impact craters as well as impact events on other Solar System bodies, such the Moon.
My aim is to answer major questions related to impact cratering and the evolution of Earth and the inner Solar System through the imaginative application of established techniques in geoscience and geochemistry as well as the advancement and refinement of analytical techniques to address previously untestable problems.
