Biological Solid-State NMR

We use state-of-the-art solid-state NMR methods, often in combination with computational techniques, to study medically important biomolecules and biomaterials at the atomic level and at native (cellular) conditions. Our main research interests are:

  • Antibiotics
  • Bioactive peptides (tissue engineering & drug delivery)
  • Membrane proteins (especially ion channels)
