I grew up in Hamburg, Germany, where I also got most of my educational training. My scientific career started with work on cetaceans, which had been my dream since childhood. I did my MSc on cetacean behavior (supervisor: Jürgen Nicolai), co-founded the European Cetacean Society, and received a PhD from the University of Tübingen, Germany, for work on the optical properties of whale eyes performed at the Max-Planck Institute of Biological Cybernetics (supervisor: Kuno Kirschfeld). I worked in the USA, Canada, and again Germany before joined the Lund Vision Group in 2000. For the discovery of multifocal lenses in animal eyes I received the Rank Prize for Opto-Electronics in 2004. In 2012 I got intrigued by the coldness and wetness of the dog nose and started the Mammalian Rhinarium Group. Many mammals have specialized nose tips, called rhinaria, covered by glabrous and wet skin. Dogs, and maybe other carnivorans, can detect radiating body heat with their rhinaria. In May 2015 I suffered a stroke in my brainstem and was temporarily unable to do any work. Now I am picking up speed again in research and teaching.
