Management Team

Dr. Christoph Ganss

Physician, CEO and founder

Dr. med. Christoph Ganss, dedicated doctor and entrepreneur, has many years’ experience in surgical techniques. He acquired in-depth knowledge and state-of-the-art medical and scientific skills both at home and abroad.

Born into a family of business owners, Dr. Ganss was fascinated by the interplay between science and business from the outset. In 2003, he set up RHEACELL's parent company, TICEBA - the world's first tissue bank for skin stem cells and now a leading biopharmaceutical company - at the Heidelberg Technology Park.

I am fascinated by what we and the entire RHEACELL team (TICEBA subsidiary) have achieved together in such a short space of time: from in-depth research through to clinical trials focusing on drug development.
