Research Interests and Science Projects

I am interested in the physical and chemical properties of extrasolar planets and in their formation processes. High-contrast  imaging and data analysis techniques help me to directly image and characterize exoplanets and their birthplaces, the so-called protoplanetary disks.

I am currently involved in several working groups of the science team for ESO's new planet finding instrument SPHERE, which is currently being commissioned at the VLT.

In addition, I am an official member of ESO's instrument science team and act as local Project Scientist for the ERIS instrument. ERIS is a 1-5 micron instrument for the Cassegrain focus of UT4 at the VLT. It will benefit from the Adaptive Optics Facility (AOF) including the deformable secondary mirror (DSM).

Finally, I am Project Scientist for the METIS instrument. METIS is the mid-infrared imager and spectrograph foreseen to be installed at the E-ELT, ESO's 39-m telescope, in the mid 2020s.

Substitute lecturer for Prof. Dr. Michael R. Meyer and PD Dr. Hans Martin Schmid. Semester and Master projects.
