    Ryan is interested in understanding genomic and environmental factors associated with psychopathology risk (e.g., depression, anxiety, substance use disorder, ADHD, schizophrenia) and their biological correlates (e.g., structural brain metrics, inflammation). He is interested int hese questions from a developmental context and studies them across the lifespan from the prenatal period to later life.  He uses a variety of methods including molecular genetics, GWAS, fMRI, EEG/ERP, pharmacologic challenge, twin studies, behavioral assessment, endocrine and inflammation assays, and self-report in both healthy and clinical populations across the lifespan. In addition to his dry lab, he runs a small wet lab that processes biological samples (e.g., saliva, blood, other tissues).
