Born in 1981, after a PhD at ETH Zurich he has been on the faculty of Technical University Munich, University of Cambridge, and currently, at the University of Milan.
He is known for his work on the atomistic theory and simulation of phonons, elasticity and viscoelasticity of liquids and amorphous solids, including the microscopic theory of elasticity of random sphere packings and elastic random networks. He also developed the Krausser-Samwer-Zaccone (KSZ) equation for the viscosity of liquids and a molecular-level theory of the glass transition based on thermoelasticity.
With K. Trachenko, he discovered and mathematically predicted that the low-frequency shear modulus of liquids scales with the inverse cubic power of the (sub-millimeter) confinement length, a law that has been observed experimentally in many systems.
More recently, he has developed a theory of phonon-mediated superconductivity which extends BCS theory to materials with anharmonicity, disorder and to high-pressure materials.
