Analytical Methods in Supramolecular Chemistry

Christoph A. Schalley is professor for organic chemistry and modular synthesis at the Free University of Berlin since October 2005. He received his PhD under the supervision of Helmut Schwarz at the Technical University of Berlin followed by a postdoctorate with Julius Rebek, Jr. at The Scripps Research Institute in California. In 1999 he joined the University of Bonn as a Liebig-Fellow of the Fonds der Chemischen Industrie to start his own independent research group. Professor Schalley has authored more than 150 publications and (co-)edited several books on mass spectrometry, dendrimers and template synthesis. He is recipient of Dozentenstipendium of the Fonds der Chemischen Industrie (2004) and the Mattauch-Herzog award of the German Society for Mass Spectrometry (2006). His research interests also include mass spectrometric characterization and gas-phase chemistry of supramolecules.
