Dr. Keator has an extensive background in data science, applied machine learning, statistics, and informatics methods for structured data exchange and reproducibility in neuroimaging.  Since 1996 Dr. Keator has been the technical director (now operations director) of the UCI Neuroscience Imaging Center (formerly UCI Brain Imaging Center) responsible for image quality control, reconstruction, and statistical analysis. Dr. Keator has been the chair of the NeuroInformatics Working group FBIRN (Functional Biomedical Informatics Research Network), leading technical personnel from member sites in developing a federated database for storing and managing subject demographics, clinical assessments, imaging, and genetics information along with the supporting metadata representations.  Dr. Keator has co-developed the Neuroimaging Data Model (NIDM) a semantic web enabled metadata format for neuroimaging currently being incorporated into popular software packages such as SPM, FSL, and AFNI.  Dr. Keator is an active part of the International NeuroInformatics Coordinating Facility (INCF) Neuroimaging Task Force and chairs the NIDM working group.  Dr. Keator directs the UCI Conte Center Informatics core, which is developing a center-wide informatics platform, based on semantic web technologies and using the NIDM standard to wrap source data across center projects and cores.
