Maurice Averner, J.D., Ph.D., is in the Life Sciences Division of NASA where he is program manager of the Advanced Life Support Program. He received his undergraduate training in chemistry and biology at Brooklyn College of the University of the City of New York, graduate training in cell and molecular biology at Brandeis University, and post graduate training at Yale University and the University of Colorado Medical School. Participation in a summer workshop in terraforming at NASA's Ames Research Center caused him to shift his scientific interests to issues of ecology, including global ecology and bioregenerative life support systems. After several years conducting research on laboratory and computer CELSS models as a staff member of the University of California, Berkeley, and the University of New Hampshire, he moved to NASA Headquarters where he assumed his present position.
