We are a theoretical group located at the Centre of New Technolgies (CeNT), University of Warsaw, Poland. We apply physical models to describe and simulate biological molecules in order to gain insight into principles governing their structure, dynamics and function. We are particularly interested in the interplay between the molecules themselves and aqueous environment they live in. To this end, we are studiyng conformation dependent protein hydration free energies, investigate the role buried water molecules, and develop new theoretical approaches to describe macromolecular hydration.
