Weingarth Lab    

Biomedical Solid-State NMR

We use advanced solid-state NMR methods to study medically important biomolecules and biomaterials at the atomic level and directly in native cellular conditions. Our main research interests are:

  • Antibiotics
  • Tissue engineering
  • Ion channels
