Nenad Ban is a Croatian biochemist born in Zagreb, Croatia who currently works at the ETH Zurich, Swiss Federal Institute of Technology, as a professor of Structural Molecular Biology. ==Career== Nenad Ban was educated at the University of Zagreb and continued with his studies in the United States where he obtained a PhD degree at the University of California, Riverside in the laboratory of Alexander McPherson. His interest in large macromolecular assemblies led him for his postdoctoral work to the Department of Molecular Biophysics and Biochemistry at Yale University where he determined the atomic structure of the large ribosomal subunit by X-ray crystallography, as part of the group in the laboratory of Thomas A. Steitz. These results demonstrated that the ribosome is a ribozyme.〔Ban N, Nissen P, Hansen J, Moore PB, Steitz TA. The complete atomic structure of the large ribosomal subunit at 2.4 A resolution. Science. 2000 Aug 11;289(5481):905-20. PubMed PMID 10937989.〕 Since 2000 Nenad Ban is a professor of structural molecular biology at the ETH Zurich. (Swiss Federal Institute of Technology). His group is studying structure and function of large cellular assemblies using a combination of crystallographic, electron microscopic and biochemical experiments.
