Physical Chemistry

My research group has been working in the development and application of computational techniques to describe systems in condensed phase. Examples of such systems are atomic and molecular nanostructured materials, confined fluids, polymeric materials and proton wires. In recent years, we have been working in the computational study of biomolecular systems in different biological environments.
