We work on different biological issues, which concern peroxisomal protein import by the AAA+ ATPases Pex1 and Pex6, electron transfer in redox proteins, and proteasomal biogenesis. Our projects are funded through individual research grants from the DFG and through projects within the “UniSysCat” (Unifying systems in catalysis) cluster of excellence. We also maintain collaborations with several national and international partners across different fields of research.
