He is Director of the Cincinnati Biobank Core Facility which provides sample acquisition, processing, storage and distribution services to researchers at the Academic Health Center. Additionally, his research investigates pathologically relevant gene expression changes in children with arthritis (JIA) with the goal is to identify diagnostic and prognostic signatures with clinical utility early in disease.
