B.A., Columbia College, Physics (1961); Ph.D. Brandeis University, Biology (1966). Robert Pollack, Professor of Biological Sciences, joined the faculty of Columbia University in 1978. His laboratory research focused on the potential utility of stable reversion from the oncogenic phenotype. His teaching focuses on the application of knowledge of the natural world to problems that require decisions that cannot be based solely on such data-driven knowledge. He was a Postdoctoral fellow in the laboratory of Dr. Howard Green at NYU Medical Center from 1966-1969; a research scientist at the Weizmann Institute of Science in 1969-70; a senior scientist at Cold Spring Harbor Laboratory from 1970 to 1975; and an associate professor of microbiology at the State University of New York at Stony Brook from 1975 until he joined the faculty as a Professor in 1978. Until 1991 his NIH-supported laboratory research focused on elaboration of his discovery in 1968 that the clonal descendants of tumor cells include genetically stable revertant cells, capable of growing into normal populations in turn. Beginning in the late 1990s, after he had set aside lab work in order to write a series of books, he has been pleased to note that other laboratories have begun to apply his discovery to the development of novel forms of cancer chemotherapy. As a result, his early research continues to be referenced in current research articles. He received the Alexander Hamilton Medal from Columbia University, the Gershom Mendes Seixas Award from the Columbia/Barnard Hillel, and held a Guggenheim Fellowship. He presented the Schoff Lectures at Columbia in 1998, which led to his third book, The Faith of Biology and the Biology of Faith. He is the Director of the University Seminars and heads the Research Cluster on Science and Subjectivity in the Center for Science and Society.
