Francesco Iachello is the J.W. Gibbs Professor Emeritus of Physics and Professor of Chemistry at Yale University. His work has been dedicated to the study of symmetries in physics through the introduction of models based on symmetry and their application to physical systems. In 1974, Professor Iachello introduced the interacting boson model of the nucleus. This model, developed in 1975–79 with Professor Akito Arima of the University of Tokyo, Japan, and based on the concept of dynamical symmetry, has brought order in the classification of complex nuclei and in the understanding of their properties. Together with Arima, Igal Talmi of the Weizmann Institute of Science in Rehovot, Israel, and Takaharu Otsuka of the University of Tokyo, Japan, he provided in 1977–78 a microscopic interpretation of the interacting boson model.
