Rorbach lab
About the group

Research projects

The central theme of the Rorbach lab is the molecular control of mitochondrial gene expression and its influence on physiology. We use genetic, proteomic, single-molecule and cryo-EM methods to reveal mechanisms and to identify novel factors involved in mitochondrial RNA metabolism. These interdisciplinary approaches help us to explore a poorly-understood area of mitochondrial biology with direct relevance to human health.

Mitochondrial RNA metabolism
Regulation of mitoribosome biogenesis
Protein synthesis in mitochondria
Mitochondrial gene expression in disease
