Biographical Info

Ester Chiessi is Associate Professor in Physical Chemistry, Department of Chemical Sciences and Technologies, University of Rome Tor Vergata, since 2021, having started the academic activity on 1989 as a Researcher in the same Institution.
Her research interests are focussed on the study of structural and functional properties of biopolymers and of biocompatible synthetic polymer systems in solution and in gel phase. Molecular modelling and simulation methods are applied to elucidate structural and dynamical properties, such as the conformational preferences of the glycosidic linkages and the role of the molecular flexibility in conformational transitions of polysaccharides.
The dynamics of non reactive processes in polymer hydrogels, such as chains fluctuations, the network responsivity to environmental stimuli and water diffusion, and the influence of cross-links density and macromolecular scaffold hydrophobicity on the hydrogel nanostructure are investigated with the support of spectroscopic, rheological and confocal fluorescence microscopy methods. Neutron scattering experiments, using European scattering facilities, are carried out to study water and polymer features in microgels. Molecular dynamics and metadynamics simulations are performed to study the solvent and polymer dynamics in hydrated matrixes and to obtain a theoretical counterpart for the available experimental results on the same systems.
She was principal investigator of about twenty national computing projects funded by CASPUR or CINECA, and participant to several national and European research projects.
