Faculty Profile


When I started studying biology at the University of Hamburg in Germany, my love for wildlife and being outdoors quickly developed into a passion for ecology and field research. As a student, I took every chance to intern in various field projects around the globe before I got stuck in Madagascar to study the reptile diversity of this fascinating island for my Master thesis. The incredible biodiversity, life in the bush, the stunning landscape and the lovely people from the community made it an easy decision to go back to this place for my PhD. I wanted to know why species are where they are and how they cope with a variety of different environmental conditions. Finally, I spent more than 2 ½ years in the bush collecting data about behaviour, activity patterns, body temperature profiles and metabolic rate of lizards. During this time, I involved local and international students in my field research and I taught students in herpetological assessments and environmental monitoring. While writing up my PhD thesis, I worked as Research Associate with the Department of Functional Ecology at the University of Hamburg, where I supervised students during eco-physiological field courses. After finishing my PhD, I wanted to learn more about applied conservation research in Africa. I switched from reptiles to big cats and worked as Field Research Manager with Cheetah Conservation Botswana where I gained firsthand experience in human-wildlife conflict particularly on commercial and communal farmland. From there, I joined SFS Tanzania in 2019 to study the human impact on the herpetofauna and the effect of climate change on species distribution.
