Hermann Ehrlich received his Ph.D. degree in 1984. He served as a postdoctoral researcher at Max-Bergmann Centre of Biomaterials and Institute of Materials Science in Dresden, and after that at Habilitation in Biomaterials at Christian-Albrecht’s University in Kiel. Prof. Ehrlich currently holds a Group Leader position at the Institute of Electronics and Sensor Materials, TU Bergakademie in Freiberg. His research is focused on marine biomaterials, biomineralogy, extreme biomimetics and technical biomateriology. Using biochemical, cellular, molecular, and analytical approaches, he and his co-workers, for the first time, discovered and characterized chitin and novel hydroxylated collagen in the skeletal formations of diverse marine sponges.
