Clinical Informatics & AI

This research now anchors a clinical informatics program: a deployed AI clinical decision-support system (evaluated across 16 clinicians), the CEBA-ADHD clinical-knowledge-graph tool (NIMH R01), and the PAWS digital therapeutic for youth cannabis use disorder (NIDA UG3/UH3).
