Predicting the mechanism and rate of H-NS binding to AT-rich DNA.

The adsorption of H-NS on DNA is studied at atomistic resolution with GROMACS. Local minima have been located by metadynamics and the transition rates computed by RETIS.

Autoionization of water.

BO-DFT simulations, via the RETIS approach, were used to study water autoionization. The mechanism(s) have been highlighted and their rate(s) quantified. Machine learning was applied to test the quality of the order parameters.
