T: 61252540


Stefan studied Biochemistry at the University of Tuebingen/Germany from 1981 to 1986. He completed his Masters in 1987 and moved to the Research Center in Juelich where he worked on amino acid producing bacteria during his PhD. He was awarded his PhD in 1991 and moved to the University of Illinois in Chicago as a research fellow of the German Science Foundation. In 1993 he was appointed as Junior Lecturer at the University of Tuebingen in the Institute of Physiological Chemistry. In 1998 Stefan was promoted to Senior Lecturer and moved to the Institute of Physiology at the University of Tuebingen. In 2000 Stefan moved to the ANU as a Senior Lecturer in the School of Biochemistry and Molecular Biology. He was promoted to Associate Professor in 2006 and to full Professor in 2008. Stefan was treasurer and council member of the Australian Physiological Society from 2005-2009.


Research interests

Membrane transporters in health and disease

Student research opportunities

Diseases of amino acid transport

Disorders of epithelial transport affecting intestinal and renal transport        Show more detail...

The role of amino acids in diabetes

Amino acid are important nutrients that regulate metabolism.        Show more detail...

Cancer metabolism

Cancer cells use amino acid to generate energy. We are investigating amino acid transport and metabolism in cancer cells.        Show more detail...

The role of phospholipid flippases in the immune system

B-cell development requires a specific distribution of membrane phospholipids. Mutations in enzymes mediating phospholipid transport can cause immunodeficiency.        Show more detail...
