Dr. Opatz joined the research group Space Medicine and Extreme Environments in 2009. After finishing medical school at the University of Erlangen-Nuremberg he wrote his doctoral thesis about gender differences in olfactory evoked potentials. He was a doctoral student of Prof. Gerd Kobal and Prof. Thomas Hummel. Today he is a medical doctor and a specialist in Anesthesiology and Intensive Care Medicine. Moreover he worked as a diving physician at hyperbaric chambers in the Indian Ocean as well as in Germany. Moreover he is the contact person for media communications and the website.
