Our Group

Our independent group is physically located at MPIA and involved in research projects from the search for protoplanets, the study of exoplanetary architectures, the characterization of exoplanetary atmospheres and the demographics of exoplanets. We are in involved and leading key activities to exploit current state-of-the-art ground-based and space-based instruments (VLT/I, LBT, JWST) and prepare the advent of upcoming ones (ELT, Roman). The group is closely collaborating with the APEx and PSF departments at MPIA and key insitutes in Europe and  worlwide.
