Christoph E. Düllmann is Professor of Nuclear Chemistry at Johannes Gutenberg University (JGU) Mainz and head of the research sections on Superheavy Element Chemistry at GSI Helmholtzzentrum Darmstadt and Helmholtz Institute Mainz (HIM), Germany and is a principal investigator at JGU Mainz in the PRISMA+ Cluster of Excellence of the German Excellence Initiative. He studied chemistry at University of Bern, Switzerland, where he received his PhD for the first chemical study of element 108, hassium. He then spent about three years at Lawrence Berkeley National Laboratory and UC Berkeley, CA, USA, to establish methods to study novel chemical compound classes of the superheavy elements, before joining GSI Darmstadt. Since 2010, he holds a joint professorship at JGU Mainz and GSI Darmstadt. His main research activities include studying the production of superheavy elements and their nuclear stability, as well as the gas phase chemical study of these elements and their compounds. He is also involved in a variety of collaborative efforts in various areas of fundamental physics, to which his group provides tailor-made samples of chemically purified radioisotopes, especially of actinide elements.
