The study of protein folding and aggregation has recently acquired a high level of technical and conceptual sophistication, in which theory, computer simulations and experiments are starting to be employed in tight combination. This book includes chapters, in all the areas, that have witnessed the major developments. Written by top experts it is unique in its comprehensive scope and coverage of all new developments in this area. The reader will obtain a perspective of the problems faced in protein folding and aggregation, and how these problems are being solved with a multidisciplinary approach using theory, experiment, and computer simulations.
