Research Abstract
Dr. David Keator, M.S., Ph.D. 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.

NIMH P50MH096889-06A1 Silvio O. Conte Center (PI: Baram) Fragmented early-life experiences, aberrant circuit maturation, emotional vulnerabilities Environmental and Biological Variation The major goals of this project are to probe the effects of fragmented early life experience on neuronal network structure and function using magnetic resonance brain imaging (MRI) of rats and humans.
NIMH 1RF1MH120021-01 (PI: Keator) In this project we develop human neuroimaging domain-specific controlled vocabularies through community engagement and to provide tools for their use in BRAIN Initiative projects. The proposed work will provide a controlled vocabulary for use by the newer BRAIN Initiative projects, incorporating such annotations into the BIDS format and hosted through the BRAIN Initiative archives such as OpenNeuro. This project will greatly improve the ability to search across and reuse datasets
