Maria-Christina Jung began her education at the Institute for Immunology at the Ludwig-Maximilians-Universität, Munich, Gottfried Fischer at the Institute of Clinical Pharmacology and Visceral Research at the University of Berne. Reinhart Zachoval began his medical training at the Max von Pettenkofer Institute in Munich, went then to Boston at the Massachusetts General Hospital and got his further education in internal medicine and gastroenterology at the Grosshadern Medical Center of the Ludwig Maximilians University in Munich. All three members of the team have worked together successfully for many years.


Maria-Christina Jung has focused for many years on the question of why an infection with liver damaging viruses (hepatitis B, hepatitis C) can become chronic, and has, through numerous scientific studies, contributed to a better understanding of the underlying mechanisms of viral infection. In addition, she is taking part in numerous clinical studies to improve the treatment of hepatitis B and hepatitis C and investigates the effect of new therapeutic approaches on the human immune system.
Reinhart Zachoval was the principal investigator of numerous studies for the treatment of chronic hepatitis B and C at Grosshadern Medical Center and was the head of a large outpatient department there for many years taking care of more than 3000 liver patients per year (including liver transplant recipients).
