The Group of BioMolecular Simulations develops and applies cutting-edge modeling and simulation methods to the study of problems of biomedical relevance.

We develop and maintain a general-purposes Coarse-Grained (CG) force field for biomolecular systems, for which we coined the name SIRAH©. The force field currently includes parameters for simulating aqueous solvent and simple electrolytes; single/double stranded DNA and proteins at Coarse Grained and multiresolution level. A substantial effort has been devoted to make the implementation of SIRAH© user-friendly and straightforward in popular simulation packages. As a result, tarballs for using SIRAH© on Amber and Gromacs (the two most popular molecular dynamics simulation packages) along with step-by-step tutorials and scripts for analysis and visualization were made available from our web site (

Latest developments include:

  • Parameters for phospholipids (In collaboration with E. Frigini and R. Porasso, Universidad Nacional de San Luis, Argentina)
  • Supra molecular water models for multiresolution simulations. These are applied to the study of entire viral capsids (In collaboration with D. Guerin and M. Costabel).
