Expertise:

Our research interests lie at the interface between Chemistry and Biology. We apply Molecular Modeling and Computational Chemistry to the understanding of ligand-receptor interactions and molecular recognition processes relevant for the design of drugs and biological probes. Our work is focused in the molecular modeling and computational study of molecular recognition processes involving Pattern Recognition Receptors (PRRs): Toll-like receptors, and Lectins. We apply computational methodologies, such as MD and CG simulations, protein-protein docking, ligand-protein docking, virtual screening and membrane simulations, to the study of the molecular mechanisms involved in the receptors functionality, and in the recognition by their ligands. We combine our work with biological and structural studies, site-directed mutagenesis, and synthesis of novel compounds, in close collaboration with experimental groups.

Role in network:
