PROJECT ABSTRACT The proposed diversity supplement requests funding for Gabriel León, a first- generation college graduate of Latino heritage (Mexican American) and Pell Grant recipient, who is a graduate student working on the NICHD-funded project, 5R01HD104801, “Prenatal Social Connection and Disruption During the COVID-19 Pandemic: Effects on Maternal and Infant Health.” The PI of that project, Dr. Darby Saxbe, is Mr. León's primary graduate research mentor and will work closely with him as he pursues his research interests in interpersonal emotion synchrony between parents and their infants. His interests are directly related to the primary aims of the funded R01 grant, which assesses how social connection benefits maternal and infant health in the wake of the COVID-19 pandemic.
