Ángel Raḿírez Ortíz was very interested in molecular modeling, in particular in developing new methods and assessing them in the CASP experiment. These studies are now continuated by David Abia, responsible of the Bioinformatics facility of the CBMSO, who is applying molecular modelling techniques in collaboration with different research groups within and outside the CBMSO, which mainly involve molecular mechanics and dynamics simulations followed by quantitative free energy calculations.
