NICHD’s Yoshinaga Retires

Dr. Koji Yoshinaga

Dr. Koji Yoshinaga recently retired from federal service after 40 years as program director in the Fertility and Infertility Branch of the National Institute of Child Health and Human Development. He joined the branch—then called the Population Research Grants Branch—in 1978 to develop a program on implantation biology and hormone action in the female reproductive tract. During his time at NICHD, he issued a number of successful funding opportunity announcements instrumental in establishing research efforts, including a cooperative program on markers of uterine receptivity and an interdisciplinary collaborative team on blastocyst implantation research.
