I am a Nanyang Associate Professor at the Division of Physics and Applied Physics of the School of Physical and Mathematical Sciences, Nanyang Technological University, head of the disordered systems group. If you are looking for an architect, try here!


Biography

Massimo Pica Ciamarra completed his Laurea degree on the Fundamental of Quantum Computing in Physics in the Department of Physics, University of Naples Federico II in 2000. He then performed a PhD in Statistical Physics of Disordered systems at the University of Naples, completing his research work as a Fulbright scholar at the University of Texas, Austin, in 2003. He worked as a researcher at the Italian National Consortium for Soft Condensed Matter (CNISM) and at the Italian National Research Council (CNR). He moved to Nanyang Technological University in 2014.


Massimo has been awarded a Young Research Award from the University of Naples, the Fulbright fellowship from the Italian-US Fulbright foundation, the Marie-Curie EU Research Network for Dynamical Arrest Award, the "Future in Research" National start-up Award from the Italian Ministry of Research, and the Nanyang Professorship within the elite scheme of Nanyang Technological University.

Research interests

The research group performs cutting-edge research at the intersection between statistical physics, soft-matter science and complex systems, and rely heavily on advanced numerical methods. The group tackles fundamental questions as well as application-inspired ones, most often in close collaborations with experimental partners. Systems and problems of interest include granular materials, fracture, earthquakes, yielding, supercooled liquids, glasses, melting, colloids, gels, tissues, active matter.

The low-frequency vibrational properties of amorphous materials are well described by correlated fluctuating elasticity theory. They are those of an elastic continuum punctuated by localised defects, the soft quasi localized vibrational modes.
