The interaction with some of SCELSE members, and the visit of some of your labs I had a couple of years ago, suggested to me the possible presence of overlaps between some of the research activities you carry out, and the research activities conducted in my theoretical/computational research group at the Division of Physics and Applies Physics at NTU. In this talk, I will give a brief overview of our research interests, that involve the investigation of complex and disordered systems through statistical mechanics approaches. I will discuss three main research subjects. The mechanical properties of amorphous materials, with particular emphasis on the role of elastic heterogeneities. The flow properties of complex fluid, including structural glasses and gels. The developing of theoretical approaches to describe many particle systems that are out of thermal equilibrium.
