Volker was born in Germany and raised in Austria, but has lived most of his life abroad. He started studying biology in Berlin, but soon transferred to Vancouver, where he completed a master’s degree investigating the evolution of vocal dialects in resident (fish-eating) killer whales. He received his doctorate from the University of St. Andrews in Scotland focused on the vocal behaviour of transient (mammal-eating) killer whales in British Columbia and Alaska and the response of harbour seals to killer whale calls.
In addition to his expertise in killer whales, Volker is interested in all aspects of animal behaviour and his research also includes looking at the behavioural aspects of other species, including bears and snow leopards.
