Christoph Cremer studied Physics at the University of Munich (LMU) and obtained a Ph.D. (1976) in Biophysics and Genetics, as well as a Dr. med. habil. degree in General Human Genetics and Experimental Cytogenetics (1983) at the University of Freiburg/Germany. Since 1983, he has been a Professor (Applied Optics and Information Processing) at the University of Heidelberg, and since 1992, he has additionally been a scientific member of the Institute for Scientific Computing (IWR) there. From 2011 to 2019, he was group leader (super-resolution microscopy) at the Institute of Molecular Biology (IMB). Since 2013, he has been an Honorary Professor (Physics) at the University of Mainz (JGU); presently, he is also a Research Associate at the Max Planck Institutes for Chemistry, and for Polymer Research (Mainz), respectively. The methodological focus of his research activities is the development and application of methods of super-resolving fluorescence light microscopy. Contributions to this field include focused nanoscopy, structured illumination, and various types of localization microscopy. As the main application field, these techniques are applied to study the nuclear nanostructure in various cell types and organisms.
