Bioanalytical infrared spectroscopy

Our group works at the intersection between basic and applied biophysics using experimental and computational methods. We study the structure and function of peptides and proteins, and the metabolism of biological cells. The time-resolved infrared spectroscopic techniques that we apply are very sensitive, as they are able to reveal the fate of single atoms in a working protein. Current projects are:

  • peptide aggregation processes relevant for Alzheimer's disease
  • molecular mechanism of enzymes (ATPase, pyruvate kinase)
  • monitoring and identifying microplastics in marine environments
  • simulation of infrared spectra
