She is especially interested in neurodevelopmental sequale following preterm birth and neonatal morbidities, and the extent to which genetic and epigenetic differences are implicated in adverse neurodevelopmental. Her research also incorporates protective factors, such as positive parenting practices, to investigate ways to promote resilience in infants who experience early adversity. Clinically, Dr. Momany conducts neuropsychological assessments for children and adolescents, provides Parent-Child Interaction Therapy for young children exhibiting disruptive behavior, and is trained as a gender-affirming provider.
