I am a geochemist and petrologist with over 18 years teaching experience. I have taught geochemistry, petrological applications, industrial minerals and exploration geochemistry, biogeochemical cycles, oceanography and stable isotopes over the years. I have particular expertise in elemental and stable isotope analysis of rocks and minerals, but also waters, soils and other environmental matrices. I started my research carrier in 1995 at Max Planck Institute, Germany. Up to now, I have trained 8 PhD students and 9 MPhil students. Currently I am co-supervisor of 7 PhD students and 9 MPhil students who are now at the final stage of their studies. I obtained 15 research grants and am working as a collaborative researcher with many international research institutes. I have published more than 70 journal articles, over 150 abstracts and one book.
