Hans-Jörg Rheinberger is a professor and researcher with a focus on history and epistemology of experimentation in the life science. By bridging the gap between the study of history and contemporary cutting-edge sciences, such as molecular biology, his work represents an example of transdisciplinarity as emerging in the present knowledge-based society. Since 1997 he has been the Director of the Max Planck Institute for the History of Science in Berlin. He is also Honorary Professor at the Institute for Philosophy and History of Science of the Technical University Berlin.
