My research applies novel isotopic techniques to advance understanding in earth, planetary, environmental and life sciences.


  • Stable isotope geochemistry and biogeochemistry of trace metals
  • Cosmochemistry and solid earth geochemistry
  • Marine geochemistry and paleoceanography
  • Novel applications of trace metal stable isotope systems for research in biomedicine, environmental geochemistry and agricultural sciences
  • Isotopic tracing of engineered nanomaterials
  • Development of new techniques of isotopic analysis
