Research Goals and Interests:

Sherika’s research broadly focuses on social and molecular determinants of adolescent externalizing disorders, including Attention Deficit Hyperactivity Disorder (ADHD) and cannabis use disorder. She evaluates predictors, pathways, and outcomes of externalizing disorders across the life course. Using the full ecological model from genes (i.e., DNA methylation) to populations, her goal is to identify risk and resilience factors for public health and public policy intervention. In this vein, she is particularly interested in Positive Youth Development (PYD) as one preventative strategy to safeguard against externalizing behaviors, especially among adolescents with chronic conditions.

Collectively, her research program on externalizing disorders, related behaviors, and interventions is at the intersection of public mental health, clinical research, and behavioral epigenetics. Her studies specifically investigate 1) childhood ADHD molecular etiology, clinical care and adverse consequences; 2) problematic cannabis use prevalence across the life course in the US, developmental risk profiles in adolescence and adulthood, and associated outcomes in a diverse cohort that includes Native American Indians; and 3) PYD among adolescents with chronic conditions.
