Describes RAND's current programs and potential new projects in the biosciences (biochemistry, biomathematics, and bioengineering) which apply the physical, mathematical, engineering, and computer sciences to biological and medical problems. These applications can clarify complex physiological mechanisms and develop better diagnostic and clinical procedures. Current studies may be grouped in three general categories: (1) physiological models and computational techniques to analyze and quantify the biochemistry of human physiological systems and phenomena; (2) analyses of the mechanics and neurophysiology of human vision, pattern recognition, and image enhancement to facilitate information transmittal; and (3) clinical applications and diagnostic techniques. Potential future projects include additional fundamental research in all the biosciences, investigations of complex biological and health care systems, and development of computer support for bioscience programs. This Memorandum does not address studies centered in experimental laboratories or those primarily concerned with the economics, sociology, or administration of health care systems.
