"Miller’s scientific and professional activities have centered around the single theme of integrating knowledge about biological and social systems. But there have been great changes over the years. His early approach to science, under the influence of Whitehead, was a mixture of philosophy and experimentation. His current research relates modern information processing technologies to living systems. The basic research consists of quantitative studies of cross-level identities among multiple levels of systems. The applications extend from the use of artificial intelligence ‘expert systems’ to measure matter, energy, and information flows in living systems to the development of an electronic University of the world."
