I am an archaeologist at the Austrian Archaeological Institute of the ÖAW with a focus on the Roman and Byzantine periods. As excavation director of Ephesos, a focus on Archaeological Sciences was a major concern for me. In several research projects, large-scale geophysical prospections, geoarchaeological investigations, a variety of bioarchaeological studies and material-specific analyses were carried out. Currently, I and my team are working on the determination of the origin and use of white marbles in the ancient world, whereby we have access to the largest database and collection worldwide. As part of these investigations, we are also working on the development of new methods and analytical processes. I am an enthusiastic learner, prefer to work in teams and really enjoy sharing knowledge with the public.
