Jared Ragland

A 2014 addition to the Marine Environmental Specimen Bank (ESB) team, Jared's research focuses on the creation of data tools to enhance and streamline the collection, processing, and reporting of environmental contaminant data. His past laboratory experience has involved measuring legacy and emerging organic contaminants in environmental matrices such as sediment and biotic tissues. His expertise primarily includes measurement of PCBs, PAHs, organochlorine pesticides, and flame retardants using gas or liquid chromatography mass spectrometry, as well as foundational metrology concepts such as detection limit calculation. Jared also has a demonstrated proficiency and ongoing interest in statistical analysis of these at-times-troublesome data.

One of the more difficult aspects in day-to-day metrology is processing of large data sets in a robust manner. Automation of these often mundane tasks dramatically reduces operator error and time-to-completion. Reducing these aspects increases confidence in the final data product, decreases training time for better student engagement, and increases the efficacy of NIST scientists by getting them back to the important parts of their projects: planning, interpretation, and reporting. Jared currently has four such data tools in development, the most recent of which is the Environmental Metrology Measurement Assistant. This tool, despite being in relatively early beta, is already having a dramatic positive impact on the way NIST does quantification for environmental metrology. Future tools will improve lipidomic data processing, field data sheet transcription, and interlaboratory comparisions, in addition to more mundane aspects of day-to-day operation such as instrument maintenance history and stock solution tracking.

Jared currently serves as coordinator for the Sample Tracking and Analytical Reporting (STAR) project. When completed in 2017, this comprehensive data tool will serve as a data warehouse for NIST's environmental metrology group, allowing access to unprecedented levels of interdisciplinary investigation into the occurrence and patterns of environmental contamination represented in the thousands of samples collected at the ESB. A large goal of the STAR project is to make these data available to the broader community, increasing NIST's presence and engagement across the globe.
