Born in Germany and raised in Austria, Dr. Deecke started studying biology in Berlin, Germany, but soon transferred to Vancouver, Canada 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. After post-doctoral research at the University of British Columbia, he returned to the United Kingdom as a Marie-Curie Fellow at St. Andrews before joining the University of Cumbria as a senior lecturer.

Dr. Deecke approaches conservation biology from an animal behaviour background. He is interested in all aspects of sound production and perception in animals, particularly in behavioural and physiological responses to anthropogenic noise.
