Research Statement

  • The ultrafast motions of atoms during chemical reactions are investigated theoretically and experimentally using x-ray absorption fine structure spectroscopy.
  • Nano-structured objects are imaged using an imaging modality based on small-angle x-ray scattering. This imaging modality is applied to medical imaging, for instance of liver cancers, as well as the imaging of nanomaterial structures and their chemical or physical transformations. 
  • The upconversion of CO2 to feedstock for the chemical industry is studied electro-chemically using nano-structured electroytes.
