A Professor in the Departments of Obstetrics and Gynecology and Cell Biology at NYU School of Medicine since 1992, Dr. Krey has also been the Director of the Embryology and Andrology Laboratories since the In Vitro Fertilization program began at New York University School of Medicine in 1993. In addition, Dr. Krey has published more than 125 peer-reviewed papers and books on a variety of research areas in reproductive biology beginning with his graduate and postgraduate training and continuing as a Fellow of the Alfred P. Sloan and Irma T. Hirschl Foundations while on the faculty at The Rockefeller University.

Dr. Krey’s post-doctoral research with Dr. E. Knobil at the University of Pittsburgh School of Medicine characterized how the ovarian hormones feedback to regulate gonadotropin secretion by the anterior pituitary gland and identified the brain regions involved in the regulation of gonadotropin releasing hormone in primates. These studies have formed the neuroendocrine bases for our current understanding of the control of ovarian function during the female menstrual cycle and played an important role in developing several clinical approaches used in IVF.

Dr. Krey’s more recent work is molecular in focus, examining how estrogen and progesterone are processed in the brain and pituitary gland and characterizing several important intracellular processes that take place during early embryonic development.
