My role is to coordinate research activities in the Luminescence Laboratory at the University of Salzburg (Department of Geography and Geology). After setting-up this new luminescence dating and rock sample preparation laboratory in 2016, my main focus is the optimization of the laboratory operation including measuring equipment and protocols. Further, I develop new capabilities for research activities as well as I generate new collaboration projects.

My research focuses on luminescence dosimetry and related methods, particularly to the analysis of geological samples and the investigation of materials for retrospective luminescence dosimetry. Due to my physical background I am interested in simulating exposure scenarios and radiation fields using Monte Carlo methods.

I am involved in different projects and international networks for scientific exchange between research institutes, universities and industry collaborations. Generally, I have a strong interest in the development of novel luminescence techniques and its applications for luminescence dosimetry and hence in fundamental understanding of the involved physical systems.
