The research activities of Dr. Giuseppina De Simone are focused on several aspects of structure/function relationships in macromolecules with a biological interest. These studies have been dedicated to a variety of macromolecular systems with different structural complexities and have been carried out by combining X-ray crystallographic methods with several other techniques, including enzyme expression and purification, enzyme functional characterization, molecular modelling, kinetic and spectroscopic analysis. Over the last ten years, in collaboration with a framework of international institutions, her research has been mainly dedicated to the structural characterization of enzymes involved in human diseases as well as the design/characterization of small molecules able to modulate their activity. Dr. De Simone is author of 120 scientific publications on international journals among which PNAS, Nat Cell Biol, JACS, Chem. Rev. She has been the Principal Investigator of several research grants from national (CNR; Regione Campania) and international (EU, Solvay Pharmaceuticals) institutions.
