Current research focus is on the role of maternal behaviors, the environment and the genetic risk of both preterm birth and poor fetal growth. The research laboratory is studying the role of stress hormones on the risk of preterm birth and the search for resilience factors that may decrease the risk of preterm birth. More recently the research group is assessing Vitamin D deficiency during pregnancy and its role in infection as a cause of preterm birth and also its role in insulin resistance in diabetic pregnancies.
Major contributions have been made in the area of maternal-fetal, neonatal physiology and endocrinology. Clinical and basic research has led to the recognition that maternal stress, both physical and psychological stress, increases the risk for preterm birth and intra uterine growth restriction. Because of this research "Maternal Stess" has become one of the four major pathways for preterm birth. The association of stress with poor fetal growth supports the concept of fetal programming for the sequent risk for adult diseases such as hypertension, diabetes and stroke now referred to as the "life course perspective" for the developing adult diseases.
Current investigations include:
Co-PI for National Children's Study to assess obstetrical events on child outcome; NIH Community Child Health Network to study community participatory research (CPR) on disparities in birth outcome; NIH Gene-Environment Interactions in Human Parturition, to identify the genetics of stress as a cause of preterm birth.
