Dr. Ingo Zebger
Research interests
- Elucidation of molecular processes, e.g. electron transfer and catalytic mechanisms in redox proteins and metalloenzymes (hydrogenases, formate, CO dehydrogenases).
- Adaptation of vibrational spectroscopic methods to study metalloproteins in solution, in the crystalline and immobilized state.
- Resonance Raman, static / time-resolved IR and surface enhanced vibrational spectroscopies (SERRS, SEIRA) in combination with electrochemical methods.
