I am a research associate at the Institute for Geography. An essential part of my research activities in arctic and subarctic permafrost landscapes is the methodical connection of different geoscientific disciplines with remote sensing and GIS as core tools as well as the integration of social science methods and data. The focus of my teaching lies in geoinformatics, physical geography and remote sensing. The scientific expertise that I acquired during my diploma thesis (2005-2006), doctorate (2008-2011) and postdoc phase (2011-2012) at the Alfred Wegener Institute for Polar and Marine Research in Potsdam, as DFG research project manager (2013-2016) and employee at the University of Leipzig (since 2013), as well as during several months of research stays in Alaska (2013) and Japan (2018), comprises three thematic priorities: (a) human-environment interactions, (b) geomorphology and landscape development and (c) (paleo-) environmental reconstruction.

My research includes geomorphology, modern and Holocene landscape development and environmental changes as well as human-environment interaction in permafrost regions of Siberia, Alaska and Northern Europe.
For the majority of my studies, I conduct geomorphological, sedimentological, hydrological and geo-ecological field research on a wide variety of landscape forms. A crucial part of my research activity, however, is the linking of various geoscientific methods and disciplines using remote sensing, geodata analysis and geographic information systems as core tools. This gives me the opportunity to capture information about processes and landscape conditions on different temporal and spatial scales.
For a comprehensive understanding of landscape processes and ecosystem connections, I always try to consider the entire landscape context. Therefore, the direct combination of geosciences and social sciences in particular has moved more into my scientific focus. I see this as an essential task to improve the understanding of landscape systems that have always been influenced by strong human-environment interactions. In addition, the combination of geosciences and social sciences represents an essential part of landscape and environmental reconstruction and also the modeling of future landscape and land use development.

As a lecturer at the Institute for Geography, I try to pass on my knowledge of modern methods and current scientific questions, my own positive research experience and my enthusiasm for various research topics to the students. That is why I consider project-specific work and method teaching to be an important part of teaching and I am very keen to contribute my own scientific activities in the supervision of students and graduates at the University of Leipzig. My previous teaching at the Universities of Potsdam and Leipzig was primarily focused on teaching the basics and applications of remote sensing, geoinformatics, physical geography and geomorphology in the form of seminars, exercises and practical courses in the field.
