Dr. Johannes W. Dietrich, M.D.

Dr Dietrich is a consultant endocrinologist at Bergmannsheil University Hospitals. He received his MD at Ludwig Maximilian University of Munich. He is a Fellow in Endocrinology at Ruhr University of Bochum, Germany and a specialist in genetic counselling in endocrinology (GfH) Düsseldorf, NRW, Germany.

He has always been fascinated by homeostasis and other concepts of biomedical cybernetics. He is particularly interested in why and how the logical structures of biological information-processing algorithms relate to their behaviour and that of the embedding organ systems. This motivated him to investigate thyroid homeostasis.

He has initiated multiple clinical trials. Key results of his work include the development of a mathematical theory of thyroid homeostasis, the development of a simulation program of pituitary -thyroid feedback control (SimThyr) that is today used in more than 80 countries for education and research, and of a mathematical method for calculating the thyroid’s secretory capacity and total deiodinase activity in vivo (SPINA).

Professor Dr Rudolf Hoërmann, MD PhD

Professor Hoërmann received his MD and PhD from the University of Munich, Germany and is a Board Certified Internist and Endocrinologist. His training included a fellowship with Harvard University, Boston, USA. During his career, Rudolf has worked in various positions at leading universities in Germany. He has also headed the Department of General Medicine, Gastroenterology and Endocrinology at Klinikum Luedenscheid, a major teaching hospital for 10 years. He currently lives at the Sunshine Coast, Australia.
