I am a soil scientist. My interest is characterizing the transformation of persistent organic pollutants in food webs using multi-element compound specific isotope analysis (C,N,H,Cl,and S) and enatiomer fractionation concepts. Currently, I am working on a method development of sulfur isotope analysis of PFOS by GC-MC-ICP-MS.
