After obtaining my Ph.D. at the University of Lausanne in the field of geology and isotope geochemistry. I have actively conducted research in the field of isotope geology and isotope environmental chemistry. I have conducted research, Tübingen (Germany), at the University of California at Berkeley, Kansas State University, and at Lawrence Berkeley National Laboratory. I have had opportunities to teach a variety of lectures in the field of environmental and isotope geochemistry at both European and US universities. My teaching experience also covers practical work in the area of geology. I have also had the opportunity to work in the area of policy management in the environmental sector for a Swiss governmental agency.
