Norbert Jakubowski studied physics at the University of Duisburg/Essen and completed his PhD in physics at the University of Hohenheim. He was a senior scientist at the Institute for Analytical Sciences, Dortmund and Berlin (from 1983 to 2009) and is now Head of BAM's Division I.1 Inorganic Chemical Analysis and Reference Materials (since July 2009). His research interests include inorganic trace and ultra trace analysis of liquids and solids by use of ICP-MS and GD-MS, elemental speciation analysis and development of elemental tags for quantitative detection of biomolecules. He has received awards including the Alan Date Memorial Award from VG Elemental, Surrey, GB (1990), Zimmer International Scholar from University of Cincinnati, USA (2005) and a Waters Symposium Award for Pioneers in ICP-MS (2006). Thomas Prohaska is professor for analytical chemistry at the University of Natural Resources and Life Sciences (BOKU). He studied Chemistry at the Vienna University of Technology, received his PhD with summacum laude in 1995 and became scientific researcher at the BOKU Vienna to built up a laboratory for elemental trace analysis. From 1998 to 2000 he was researcher at the EC-joint research center IRMM in Belgium. Peter H. Roos studied biology at the Ruhr-University Bochum(Germany) with a focus on plant biochemistry. After his PhD thesis he turned towards biochemical processes in animals and humans (Universities of Dusseldorf, Aachen and Bochum) and focused his research on effects of toxic compounds in mammals and on carcinogenesis. He is currently lecturer in biochemistry and leader of the Molecular Toxicology group at the Leibniz Research Centre for Working Environment and Human Factors (Dortmund). Lothar Rottmann obtained his PhD in Analytical Chemistry in 1994 at the University of Regensburg under the supervision of Prof. Klaus Heumann. There, he developed a method for online isotope dilution of an HPLC/ICP-MS system. Afterwards he joined the R&D department of Thermo Fisher Scientific where he started as a research scientist. Since 1995 he has been a project manager, responsible for the development of several high resolution sector field instruments. Charles B. Douthitt is an isotope ratio specialist at Thermo Fisher Scientific, USA and Dr. Stephen Guilfoyle is a mass spectrometry specialist at Nu Instruments Ltd., UK.
