Stuart A. Newman is a professor of cell biology and anatomy at New York Medical College, Valhalla, New York. His early scientific training was in chemistry (A.B., Columbia, Ph.D., University of Chicago), but he moved into biology, both experimental and theoretical. He has contributed to several fields, including biophysical chemistry, embryonic morphogenesis, and evolutionary theory. His theoretical work includes a mechanism for patterning of the vertebrate limb skeleton based on the physics of self-organizing systems, and a physico-genetic framework for understanding the origination of animal body plans. His experimental work includes the characterization of the biophysical process of “matrix-driven translocation” of cells. Newman has also written on ethical and societal issues related to research in developmental biology and was a founding member the Council for Responsible Genetics (Cambridge, Mass.). He is an external faculty member of the Konrad Lorenz Institute, Klosterneuburg, Austria, and editor of the institute’s journal Biological Theory.
