Mauricio G. Mateu is a Full Professor of Biochemistry and Molecular Biology at the Universidad Autonoma de Madrid (UAM), and a Group Leader at the Centro de Biología Molecular ""Severo Ochoa"" (Spanish Research Council-UAM). He combined training in biochemistry, molecular virology, and protein engineering in three prestigious laboratories, respectively led by Profs. Severo Ochoa and Esteban Domingo in Madrid, Spain, and Alan R. Fersht in Cambridge, UK, to establish a research line on the structural basis of virus function. His group uses protein engineering and biological, biochemical, and biophysical approaches, including atomic force microscopy, to understand the relationships between atomic structure, conformational stability and dynamics, physical properties, and biological function of viruses. His studies on viruses during the last 35 years have involved multidisciplinary and interdisciplinary collaborations with theoretical and condensed matter physicists, organic chemists, biochemists, structural biologists, biophysicists, and molecular virologists. He is the author of over 150 scientific publications, including over 110 original research articles.
