In 2002-2003, he developed and coordinated situation awareness reporting for the National Smallpox Vaccination Program integrating data from vaccine distribution, immunization records, and VAERS.
In 2003, David became Director of Operations for the BioSense program in NCPHI, coordinating the roll-out operations of the BioSense interface to state/local health departments, and serving as liaison to CDC’s Emergency Operations Center. These duties included consulting with state/local health departments on their outbreak detection and response needs, consulting with other federal agencies on integration of data to support outbreak detection, advising on data quality assurance and analytical processes in clinical encounter data, and implementing the Situation Awareness Unit in the EOC for pandemic flu exercises.
In 2007, David became the Associate Director of Operations for NCZVED’s Office of Critical Information Integration and Exchange, developing and operating public health “fusion center” monitoring and reporting, and leading the process to produce daily reports summarizing local, national, and international public health events of concern. In 2009, David moved to NCIRD’s Informatics Office, serving as Data Management Lead and Acting Deputy Director, and supporting the data management and data quality assurance needs of NCIRD and the H1N1 Influenza Task Force.
In 2012, David joined the newly formed Analytic Tools and Methods Branch as Branch Chief, initiating the Analytic Data Management Unit to provide data acquisition and analytical support of external clinical data sources (CMS, HCUP, AHA) for CDC-wide use, as well as coordinating on-going activities of the Epi Info Team and the Population Health Metrics Team.
