We strive to understand the molecular-scale perspectives of interfacial processes, e.g. interactions of inorganic/organic/biological species at solution-mineral interfaces. By taking a multi-scale approach from molecular, microscopic, macroscopic, to field scale, our current research focuses on the following topics:

  • Contaminant fate and transport
  • Metal redox cycling
  • Biomineralization

We employ a wide range of laboratory, microscopic, and spectroscopic techniques, such as:

  • Synchrotron X-ray techniques: spectroscopy (XAS), diffraction/scattering (XRD/PDF), microscopy (XRF/STXM)
  • Microscopy and surface sensitive techniques: scanning/transmission electron microscopy (SEM/TEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS)
