Welcome to my homepage!

I'm currently a post-doctoral researcher at NCAR in Boulder

Past changes in solar activity and the solar influence on climate as well as the reconstruction of past changes in the geomagnetic field intensity and in the carbon cycle are my main areas of interest.

This is one of my favourite pictures that I took on a scientific cruise to Sanae IV, Antarctica. It shows two curious Adelie penguins. They came to investigate our ship when we were stuck in the sea ice for several days
