Lives in "Habnen", specifically  in the small village  called Kirkehamn on the island of Hidra in Vest-Agder, south-western Norway.  I am married to Lise and work as a teacher at Lister High Schooll (division Flekkefjord)  where I teach biology and science, a job that I am very happy with.  I am also part time  employed  in NDLA - a national project creating online learning material fin biology for  high school students (www.ndla.no)  An interest in nature and biology have been there since boyhood. For many  years I have worked with "the Coral Reef Aquarium", coral reef biology and tropical  biology. Systematics, biological  diversity and, above all, the preservation of pristine  areas is important to me. Some of my  photographic interests are therefore directed to "species and environmental documentation ".  Moreover, evolutionary biology, is anorther field of great interest. The story of how life  on Earth originated and continues to evolve fascinates me a lot. Human evolution and  our early ancestors in East-Africa, is to me one of the most fascinating subjects that  one can study today. Charles Darwin and his fundamental theory on evolution is also  topic that i over and over again keep coming back to.  After many years of underwater photography, the photographic interest has now  moved on to land. Nature photography is excellently combined with  travel, and both me  and my wife love to travel. We try to visit as many corners of the World  as possible,  and through these pages, I hope  to share some of our experience with you .....
