Abstract
German Rivas is an executive editor of the IUPAB Biophysical Reviews journal based in Spain. As the head of the Department of Structural and Chemical Biology at the Center for Biological Research (CIB) Margarita Salas (one of the largest research institutes devoted to life sciences of the Spanish National Research Council (CSIC)), he leads a research program aimed at understanding the structure function relationship of large macromolecular complexes (involved in bacterial cell division) when placed in physiologically complex and "crowded" media toward their reconstitution from the bottom up in cell-like compartments. In this "Meet the Editors'" piece, he briefly describes his research interests and history.
