The paper examines how environmental exposures affect whole-brain functional connectivity and cognition in youth using machine learning and the ABCD Study data.

This study identifies four substance use trajectories in youth and links them to dopamine-related neurobiology, impulsivity, and inhibitory control during adolescence.

The paper introduces a scalable method to estimate basal ganglia brain tissue iron using fMRI data, validated across developmental datasets and applicable to large-scale repositories.

The paper examines how childhood maltreatment affects brain structure in 3,711 individuals with MDD and PTSD, finding age- and sex-specific brain morphometric differences.

The paper examines how striatal dopamine maturation supports habitual behavior development from adolescence to adulthood using longitudinal data.

The paper examines age-related changes in basal ganglia iron levels in neonates using rsfMRI data, finding postnatal age associations in specific subregions and preterm birth effects.

This study examines how puberty influences fronto-striatal functional connectivity and its relationship to inhibitory control in adolescents.

The paper curates and provides analysis-ready diffusion MRI data for pediatric brain white-matter research, including automated quality control using a trained neural network.
