Dr. Müller studied Biology with particular focus on Animal Behaviour at the University of Zürich (Switzerland). After two internships with field work in the Kalahari (South Africa) and in Yellowstone National Park (USA), he then went on to study vocal and olfactory communication of banded mongooses in Queen Elizabeth National Park (Uganda). For this work he obtained his doctoral degree from the University of Zürich in 2007.
As a postdoctoral researcher, Dr. Müller initially continued studying the banded mongooses in Queen Elizabeth National Park, as an independent research fellow based at the University of Exeter (UK). In 2010, he moved to Vienna where he has been studying the cognitive abilities of domestic dogs, first at the University of Vienna and then at the recently founded Messerli Research Institute. During his career, Dr. Müller has written or co-authored 20 publications in peer-reviewed scientific journals. Among them is a recent article entitled “Dogs can discriminate emotional expressions of human faces”.
