Johanna IrrgeherJohanna Irrgeher is currently postdoctoral researcher in the field of analytical chemistry at the VIRIS Laboratory for analytical ecogeochemistry at the University of Natural Resources and Life Sciences Vienna (BOKU). She holds a master degree in bioechnology from BOKU Vienna and obtained her PhD granted by the Austrian Academy of Sciences in 2013 with honours for her work on stable strontium isotope ratio analysis by (LA)-MC ICP-MS. During her PhD she was visiting researcher at the Institute of Isotopes in Budapest (Hungary), the National Cheng Kung University in Tainan (Taiwan) and the National Research Council Canada in Ottawa (Canada). Since 2014 Johanna is associate member of the IUPAC committee on isotope abundances and atomic weights as well as the IUPAC subcommittee on isotope abundance measurements. Her current research focuses on analytical method development for elemental and isotopic analysis in the field of analytical ecogeochemistry dealing with both aquatic and terrestrial ecosystems.
