Carsten studies protoplanetary disks, exoplanets and solar system objects. His goal is to understand the physics of planet formation processes that are happening in protoplanetary disks, and to link these processes to the planetary system architectures that are currently discovered. He focusses on dust particles in disks that can be observed by high-contrast, high-spatial resolution imaging from visual to submillimeter wavelengths, and studies how these dust grains grow into comets and planets. Carsten teaches the introductory course on Astronomy and Astrophysics in the Bachelor, as well as classes on Star and Planet Formation, and on Exoplanets.
