Research

Paleomagnetism mainly uses the magnetic characteristics of a rock to reconstruct the directional information of the magnetic field during formation of the rock. Obtaining this information enables us on one hand to reconstruct the position of continental plates back in time. On the other hand, we can use the paleomagnetic information to correlate sections with each other and with a global polarity timescale, which is based on the ocean magnetic anomalies, because the magnetic field reverses its polarity in a non-systematic way. This magnetostratigraphic approach has a huge potential in combination with absolute dating and biostratigraphy to reveal information about duration, sediment accumulation rate and the basic age information where no volcanic remains are present.

Concerning the first topic, I worked for example on the paleogeographic reconstructions of the Central Asian Orogenic Belt during the Paleozoic and the position of the Australian Cratons during the formation of the supercontinent Nuna.

Additionally, I worked since the start of my career on magnetostratigraphy of Neogene terrigenous sedimentary rocks mainly in the Caucasus, South Germany and Greece. Most of these studies were related to dating sedimentary sequences of important fossil localities and/or related climatic signals.
