Helmut Cölfen, Ph.D., is Full Professor of physical chemistry at the University of Konstanz. His research interests are in the areas of nucleation, classical and nonclassical crystallization, biomineralization, synthesis of functional polymers, directed self assembly of nanoparticles, and fractionating methods of polymer and nanoparticle analysis, especially analytical ultracentrifugation. His group has made contributions in high resolution particle size analysis with Angström resolution in solution, mesocrystals, nonclassical crystallization, CaCO3 crystallization, and additive controlled crystallization. Recently his group identified prenucleation clusters as stable species even in undersaturated CaCO3 solution and found an alternative crystallization pathway for CaCO3 via the aggregation of the prenucleation clusters. He received several awards including the Hermann Schnell price of the German Chemical Society for the best young researchers in macromolecular science and the Steinhofer lecture at the University of Freiburg. He has recently been listed in the Thomson Reuters list of top 100 chemists worldwide for the years 2000 to 2010, a list including several Nobel laureates.
