Dr. Kia L. Ngai has worked in relaxation and diffusion in disordered and partially ordered systems across many disciplines for 25 years. He has authored or co-authored over 300 publications in archival journals. His works have been cited widely.Dr. Ngai has also written a chapter in the textbook, Physical Properties of Polymers, 3rd edition (Cambridge University Press, 2003); two chapters in Physical Properties of Polymers Handbook, edited by James E. Mark (Springer), and a chapter in Science and Technology of Rubber (Elsevier). He was the originator and organizer of the following large-scale international conference series entitled "International Discussion Meeting on Relaxations in Complex Systems": 1990, Herklion, Crete, Greece; 1993, Alicante, Spain; 1997 Vigo, Spain; 2001, Hersonissos, Crete, Greece; and 2005, Lille, France. I served as the editor of the Proceedings of each of these Meetings. The proceedings are published as refereed papers in the Journal of Non-Crystalline Solids (Elsevier) in 1991, 1994, 1998 and 2002.

• Introduction.- Universal Relaxation and Diffusion Properties in Complex Systems.- Experimental Evidences.- Computer Simulations.- Theoretical Modeling and Interpretations.- Many-Body Relaxation Dynamic and Relation to Chaos.- Glass Transition and the Glassy State.- Role of Thermodynamics, Volume, Entropy and Temperature.- Polymer Viscoelasticity.- Ionic Conductivity Relaxation in Ionically Conducting Materials.- Relaxation and Diffusion at Nanometer Scales.- Relaxation in Biomolecules.
