Research Interests

I am interested in biogeochemical cycles of major and trace elements across a wide range of spatial and temporal scales, and their implications for key processes that have shaped surface environments of our planet throughout geological history. I specialize in isotope geochemistry. My current research includes several related components:

  • Development of new techniques for isotope analysis;
  • Experimental isotope geochemistry for non-traditional stable isotopes; 
  • Chemical oceanography
  • Reconstructions of paleo-climate and environment using stable and radiogenic isotopes (in particular, ocean circulation and redox state of past oceans)
