I was born in the beautiful city of Freiburg, in southern Germany. After school, I lived a year in Norway, studied biology at the Universities of Mainz, Tübingen and Sussex and I got my Diploma (1989) and my PhD (1993) i Biology. For my PhD thesis, I studied flight control and visual orientation in a stingless bee, in Porto Alegre in southern Brazil.
After the birth of Sebastian (1993) and Helena (1994) I started a new project and studied hawkmoth colour vision. 1997 the entire family moved to Canberra. where I worked on orchard butterflies and their complex colour vision system. In 1998, I joined the Vision Group in Lund where I now work as a Professor of Sensory Biology.
I am interested in general principles and evolution of colour vision, and on the trade-offs animals make between colour resolution, spatial vision and sensitivity. Over the years, I have been working on many different animals including horses, seals, geckos, birds, butterflies, moths, bees and velvet worms.
Besides research, I am also interested in teaching, and here I strongly believe in research-based teaching, and in supervision and coaching of students who start developing their own research interests.
