Alessandra was educated as a chemistry at the University of Milano. After a Ph.D.in quantum chemistry, she got a Marie Curie Fellowship to work on biomolecular force fields at Groningen University. Then, she moved to Goethe University and MPI for polymer science in Germany, where her main focus were nucleic acid simulations and coarse grained models, and later, to Sweden (Karolinska Institute) to continue to work nucleic acids.
Her main research interest is to elucidate the molecular interactions that govern cellular processes using biomolecular simulations. A large part of her work focuses on the development of molecular models both at the atomistic and coarse grained levels to better describe how biomolecules interact. She has wide experience both in combining experimental and simulation techniques and in combining molecular models (multiscale apporach) to solve biochemical and biophysical questions.
