Curriculum Vitae


I got my Ph. D. in Physics in 2006, at University of Rome "Tor Vergata". I have been post-doc at NNL-CNR in Lecce (2006-2008), at the Universidad del Pais Vasco (2008-2010), and at present I am a researcher at the Italian Institute of Technology - IIT in Rome.



Research Interest


My research activity, in the field of theoretical solid state physics, focuses on ab initio study of reduced-dimensionality systems (surfaces, interfaces, nanocrystals) and of organic-inorganic hybrid systems, paying particular attention to their applications in nanotechnology. Methods are mainly based on Density Functional Theory, both with all-electron, localized basis and pseudopotential-plane waves approaches. Excited properties methods rely on TDDFT, and Many Body Perturbation Theory based techniques including GW, sc-COSHEX, BSE.


Current Research Projects


My work is at present focused on two main reseacrh lines. The first one is the investigation, via classical molecualr dynamics, of membrane proteins, to understand their behaviour in presence of ligands, and of protein-protein interaction. The second topic is related to material science, in particular nanoscience, with the study via MD and ab initio electronic methods of metal nanostructtures and their interaction with organic and biological molecules.
