Prior to the supervisory position, he was Subject Matter Expert (SME) team lead in the microwave measurements laboratory at NPSL supporting both coaxial and waveguide transmission line components from 10 MHz to 50 GHz. He and his team were responsible for one and two port S parameter measurements using microwave commercial Vector Automatic Network Analyzers (VANA) and National Institute of Standards and Technology (NIST) 6-Port VANAs. His team was responsible for RF power measurements using the NIST Direct Comparison Measurement System, NIST 6-Port VANAs, NIST RF Power Standards and Power Density measurements using a NIST constructed anechoic chamber and TEM cell. He was also responsible for microwave noise measurements and time & frequency measurements. 

• Developed measurement software to perform automated measurements with error analysis on HP 8510 Vector Automatic Network Analyzers and NIST 6-Port VANAs.

• Developed measurement error budgets for microwave measurements for preparing reports of calibration using NIST artifacts as standards for traceability.
• Experienced measuring phase noise using NIST Phase Noise Measurement System developed by Dr. Fred Walls at NIST.
• Responsible for time and frequency measurements using cesium standards, GPS rubidium standards and using the NIST Frequency Measurement and Analysis Service (FMAS).
• Performed calibration factor measurements on microwave radiation hazard probes in anechoic chamber and TEM cell. 

Other background:

• Registered Lead Auditor for Joint Navy Audit Certification (JNAC) Team for 9 years
• Served as National Conference of Standards Laboratory International (NCSLI) Measurement Comparison Program Committee Chairman.  The committee published NCSLI RP-15 “Recommended Practice for Inter-laboratory Comparisons.”
• Awarded Naval Air Systems Command Associate Fellow in 2003
• Awarded Senior Member of Institute of Electrical and Electronics Engineers in 1999
• Technical manger at NPSL for Measurement Assurance Program in support of Egyptian Air Force MECC laboratory, managed measurement data, performed SPC and provided reports to customer. 
• NPSL representative on NIST/ DOD Calibration Coordinator Group (CCG) for Microwave Laboratories. Contributed historical and technical information for NIST Special Publication 980, “Partnership for Advanced Measurement Standards: The Calibration Coordination Group (CCG) of the Department of Defense and the National Institute of Standards and Technology”
• NPSL Coordinator for NAVAIR Depot Round Robin Proficiency Testing Program. (RRPT). Coordinated pilot tests for RRPT with NAVAIR depot calibration laboratories

James graduated with a Bachelor of Science in Electrical and Electronics Engineering (BSEEE) from North Dakota State University, Fargo, ND in 1981. While at NPSL he pursued graduate level studies in Microwave Communications, Solid State RF Amplifier Design and Antennas and Propagation at San Diego State University. 

James served in the U.S. Navy for 6 years active duty in the Advance Electronics Program as a Cryptologic Technician, Maintenance (CTM).  He completed Electronics Technician Class A School, Crypto Repair School and other Class C Schools. Duties consisted of installing and maintaining cryptographic, teletype and communications terminal equipment including AUTODIN/DSSCS. He held a Top Secret Sensitive Compartmented Information (SCI) Security Clearance.
