The Branch celebrated its 25th anniversary in 2017. We were joined by the NICHD Scientific Director, Dr. Diana Bianchi and the NICHD Intramural Division Scientific Directory Argyrios Stratakis. Leaders from the Detroit Medical Center, Wayne State University, the city of Detroit and our US Congresswoman joined in our celebration, among others. This milestone was a meaningful celebration of the work that the PRB has advanced on behalf of mothers and children in the study of perinatology, where we have participated in the care of over 25,000 pregnant mothers and their unborn children. Our work has earned a national and international reputation for its scientific achievements and original contribution. The research of our multidisciplinary team has improved the understanding of obstetrical disease and changed the practice of medicine.
