Castillo's contributions further our understanding of the elastic properties of rubber, the behavior of electrons in certain disordered solids, and the motion of defects in certain crystals.
Lately, he has been interested in understanding ``Physical Aging''. This phenomenon is characteristic of glasses and other materials that slowly change their properties with time, even when the temperature, pressure, and other external conditions are kept constant. Most of his recent work on aging has involved numerical simulations using Monte Carlo and Molecular Dynamics methods.
When he is not doing research or teaching, Castillo enjoys hiking, playing with his dog Bear, and swimming.
