A theoretical physicist who, with Giancarlo Ghirardi and Tullio Weber, proposed a common dynamical description of microscopic systems and macroscopic objects. Their Ghirardi-Rimini-Weber theory modifies ordinary quantum evolution so that widely separated macroscopic alternatives do not persist indefinitely. The GRW amplification mechanism connects a weak microscopic modification to strong macroscopic localization.[ref]

A theoretical physicist studying dynamical approaches to the measurement problem. His review with Giancarlo Ghirardi develops models in which nonlinear and random modifications of the Schrödinger equation account for localization of macroscopic objects while retaining ordinary microscopic predictions to high accuracy. Such models make the transition from quantum behavior to classical behavior part of the dynamics.[ref]
