  Chemical Sensing and Chemometrics Section    

The principle function of this section is to conduct research that will lead to new and basic understanding of chemical reactions and data analysis methods as applied to chemical sensing and detection. Projects include the study of trace metal speciation, chemical & biological detection, hazardous chemical detection, intelligent data fusion, chemometrics applied to sensor systems and analytical methods.  This program consists of research projects involving novel state-of-the-art methods for the detection of hazardous chemicals, Navy mobility fuel properties, trace chemical analysis, and damage control events such as fire and flooding. These R&D projects require expertise in basic chemical analysis, instrument design, method development, computational modeling, chemometrics, and system verification.  The research areas address environmental and workplace detection needs using chemical sensors, personal dosimetry, and area monitoring.  Design and development of individual sensors and sensor arrays is an emphasis of section research. Another major area of research is the application of artificial intelligence techniques to data interpretation problems associated with hazardous material detection and improved situational awareness.  A key focus of this research is the analysis of sensor array data using statistical multivariate methods such as pattern recognition methods and neural networks.  Video image analysis using machine vision is also a major focus.  Novel data fusion methods are being used to convert data into information that can be more effectively used for the detection of chemicals, identification of fuels, and damage control events. A significant function of the section is in the development of novel spectrometric methods and analytical methodologies.  As a member of the Navy Fuels & Lubes Cross-Functional Team (CFT), this section conducts research and provides technical support in a wide range of Navy fleet fuel issues.  This includes basic research in the reaction mechanisms of fuel thermal and storage stability; metal cataliyzed autoxidation mechanisms; characterization and utilization of bio- and synthetic fuels, and the formulation of  novel chemometric algorithms to enable the development of sensing technologies for automated fuel quality diagnostics and prognostics.
