M.D., Ph.D.

About me.

For many years I was a Professor of Genetics / Biology and a M.D. specialist for internal medicine; I am now retired.

In spite of the fact that I decided to study medicine, I’ve had a lifelong interest in the animal kingdom and later in life I also became interested in the study of botany.

Thus, the change from Internal Medicine to Biology occurred only later into partly interdisciplinary professional work. This work stimulated multiple collaborations with zoos.


Out of all animals, I chose chelonian biology as my second profession solely based on practical considerations; theoretically because of their evolution and in practice because of their husbandry. 

Between 1965 and 2000, more than 40 species have reproduced in my personal collection. Physiological and their medical care have played an important role.

In 1993, “AGARK” was founded, which is a close group of veterinarians dedicated to the diseases of amphibians and reptiles, and is also a sector inside the DGHT (“Deutsche Gesellschaft für Herpetologie und Terrarienkunde”) where I am a member. Further memberships include: Austrian Society for Herpetology (ÖGH), German Zoological Society (DZG), Society of German Natural Scientists and Physicians (GDNÄ), Society of Human Genetics (GfH), Tortoise and Freshwater Turtle Specialist Group (TFTSG), Conservation Breeding Specialist Group (CBSG) of the International Union for the Conservation of Nature (IUCN), and Turtle Survival Alliance (TSA).

My main goals have always been and will continue to be reproduction biology, and to guarantee this physiology and medicine.
