About Me

I am a postdoctoral researcher at ITC in the department of Earth Observation Science (EOS). I have a background in (Geo-) Ecology and Biogeography, but since my diploma thesis on the infamous Asian Tiger Mosquito Aedes albopictus has my research been focused on spatial and spatio-temporal patterns of disease vectors and the pathogens they transmit. Working on a topic where so many different disciplines overlap makes for an exciting mix of concepts, mechanisms and methods. Being the main organizer of our talk series, the GeoHealth Hour, is a great opportunity to further broaden my horizon.

Ever since my first publication (on the extrinsic incubation period of dengue), making data accessible and digestible to others has been a major driver of motivation for me. The most recent result of this is ENDIG, an interactive geovisualization of European surveillance systems for communicable diseases.
