RESEARCH SCIENTIST,
Internet Applications / Software / Databases (1999 – Present):
Developed internet-based applications (real-time controls, reports and queries, charting, engineering algorithms) in support of energy-related databases, building systems and controls, data collection processes, and equipment simulators. Coded dynamic content using server-sided ASP (VBScript) and client-sided JavaScript (using Visual Studio / InterDev). Served applications using IIS of Windows 2000 Server. Developed executables and Windows services in VB and VB.Net to facilitate automated feeding of databases and to monitor and resolve server and data process status issues. Projects include: GIS map server and application for federal facilities; unified interface to corporate facilities performance databases; real-time stack emissions monitoring; residential building standards compliance evaluator; air conditioner simulator and calculator; real-time building systems load-shedding controller and viewer; power industry activities database application.
Developed database tools for managing and tracking energy, services, and costs associated with facilities operation (150 buildings) at Battelle PNNL. Implemented through a multi-user front-end plotting/reporting tool for building managers, a front-end data-processing tool for administrators, and a back-end relational database. Tools were developed in Microsoft Access. Used Microsoft VBA and SQL in developing custom plotting, user-controlled queries, and data transformation techniques. Worked with customers to determine requirements and produce design documentation. Developed a context-sensitive compiled help system.
Developed internet application for dynamic
graphical display of telemetry (weather) data. Wrote and scheduled
Perl scripts to glean/parse data from various web sites and feed a live
database (updated every 5 minutes). Designed a
web-based graphical viewer to the database using ASP and COM based charting
software. Incorporated ODBC,
Energy Research (1992 – 1999):
Conducted field-based performance
assessments of energy and water conservation measures. Compared thermal and economic performance of new and existing
technologies. Designed data-acquisition protocols and executed
monitoring studies. Optimized sampling methods.
Combined deterministic and statistical methods to analyze the
impact of in-use operating conditions. Performed
time-series, inference, and regression analysis. Projects include:
Performed analytic studies of HVAC system components. Developed HVAC system simulations and regional aggregation methodologies to quantify the interactions between equipment, climate, buildings, and loads. Analyzed thermal and cost performance for selecting new technologies. Projects include: Commercial equipment standards for air conditioners, furnaces, and boilers; standards for residential duct insulation, study of ventilation systems for manufactured houses; estimates of commercial HVAC distribution energy.
Provided consulting support on the application of laser Doppler velocimetry (LDV) systems in making measurements of fluid velocity. Investigated oscillating-jet flow from microscopic orifices and the associated enhancement of heat transfer. Adapted a conventional LDA system for use with fiber optics.

techniques. Participated in design of custom
built LDV optics for users with special requirements. Used optical design software (KIDGER) to predict performance of LDV
systems. Conducted in-house fluid velocity
experiments on models from customers. Pursued government research
grants; wrote proposals and developed associated products. Presented measurement-technology developments at engineering
conferences. Traveled to universities and
customers' facilities in North America and
