Proceedings of a NATO Advanced Research Workshop held in Granada, Spain, October 1991, with the objective of bringing together physicists and biologists with a common interest in pattern growth and in applying new tools across the areas of their disciplines to explore the similarities and differences in their subjects. The contributions address topics in cell colonies; surface and interfaces; diffusion limited aggregation, viscous fingering and fracture; cellular patterns; dynamical systems; self replication; self organization; and measurement and characterization.
