Once grown up, Klaus graduated from the University of Vienna in microbiology and then did his doctoral work in zoology/neuroscience at the Max Planck Institute for Brain Research in Frankfurt. He went on to research positions in California, Japan and Australia.
Since 2014 Klaus has been based in the Philippines as an independent scientist, nature photographer, popular science writer and scuba instructor (PADI Tech Deep instructor and IDC staff instructor). He is a visiting scientist at the marine conservation NGO People and the Sea and at the University of the Philippines Marine Science Institute (summer of 2017), as well as an affiliate researcher at the Neurolinx Research Institute.
As a photographer, Klaus loves to shoot birds and the underwater world. To him, nature photography is the ideal intersection between science and art.
