The research in our group focuses on exploring DNA-proteins interactions and biophysical/biomechanical properties of viral capsids & cells. The aim is to work with increasingly more complex assemblies of proteins in order to investigate the emergent properties from these systems. This approach bridges experimental systems biology and single-molecule manipulation techniques. We use a variety of techniques such as optical tweezers, AFM and single-molecule fluorescence as well as combinations of these techniques. The data obtained are related to biochemical studies and used for theoretical modeling.
