[citation needed] Since 1978 he has been at Yale University, where he is at present J. W. Gibbs professor for physics and chemistry.
[citation needed] Iachello received the Chiaudano prize in 1968 and was a Fulbright Fellow in 1964.
The underlying concept is to derive a model with pairs of neutrons and protons instead of unpaired nucleons.
In an extension of the model, the analogous effect with unpaired fermions has a description using supersymmetrical algebras.
[3][4] In recent times he has worked mainly on the investigation of the quantum mechanical dynamics of molecules (e.g. quantum phase transitions, polymer dynamics) with algebraic methods, on which Iachello already began to work in 1981 (Vibron Model).
