Professor Georg A Holländer was trained in both Paediatrics and Experimental Immunology in Switzerland and the United States of America. He has held academic positions at Harvard Medical School and the University of Basel, Switzerland, before he joined the University of Oxford in 2010. He is interested in the development and function of the immune system in health and disease. His particular scientific focus concerns the molecular and cellular control of thymus development and function; which has also led to his interest and support of the potential use of Chitin in such medical and pharmaceutical practices. Ross Group Plc welcomes Professor Holländer as its Senior Independent Non-Executive Director.
