I am a vet from Germany with a profound interest in the biology of wild mammals, preferably those with flippers or a pouch. I am especially interested in pathogens and diseases in wildlife species and their interface with people. As the recent emergence of a number of zoonoses like SARS and Ebola revealed, public and wildlife health are increasingly linked, emphasizing the importance of the multidisciplinary “One Health” approach.



Preliminary PhD project title: “Investigations into the microbe community in the respiratory tract of humpback whales (Megaptera novaeangliae) by analysing exhaled breath condensate (EBC)”


Whales are considered as sentinels of the health status of our oceans. However, whales are hard to study. A relatively recent approach is to sample their blow. Hormones could already be detected in it. The potential of the new method is even more promising though: We aim to characterize the microbial communities, potential pathogens and immune parameters of their respiratory tract. Consequently, we hope to gain some insight into the health and immune status of the population of humpback whales migrating along the Australian east coast.


I received my degree in veterinary science at the Free University Berlin in Germany. Following this, I gained some wildlife medicine experience at several Wildlife hospitals in the US and Australia. Subsequently, I worked as a researcher at the clinic for Zoo Animals, Exotic Pets and Wildlife at the University of Zurich, Switzerland. At the same time I received a postgraduate research degree on methane production and digestive physiology of non-ruminating foregut fermenting herbivores such as pygmy hippos, sloths, peccaries and kangaroos. For the research project on kangaroos I spent 10 months at the UNSW arid zone research station Fowlers Gap.
