Manuel Prieto (PhD, 1981, Habilitation, 1993) is Full Professor of Instituto Superior Técnico (IST) of Universidade de Lisboa (Portugal). The work is centered on the application of state-of-the art fluorescence methodologies, both in ensemble average and under the microscope, to retrieve topological and dynamic information on biological systems, using quantitative approaches. Examples of the broad research interests are membrane biophysics such as phase diagrams, detection and study of membrane nanodomains, lipid-protein/peptide and lipid-DNA interaction, amyloid fiber formation, and ion channels. He has a strong record of participation in international scientific organizations: Council Member of LAFEBS (Latin American Fed. of Biophys. Societies), Science Europe- Sci. Committee, FEBS Publications Committee, Initiative for Science in Europe. Also, he was Faculty Member of the UNESCO Chair of Biophysics (Argentina, 1999-2003), President of EBSA (European Biophysical Societies' Association), and President of the major Biophysics organization, IUPAB (International Union of Pure and Applied Biophysics).
