Professional experience:
2006-Present: Consultant to private companies in electrical engineering in power electronics (inductors and transformers), and medical electronics (RF isolation) and transcutaneous energy transfer systems (TETS).
1987-2006: Senior engineer, KAPL, Inc. Div. of Lockheed-Martin Corp. (formerly Knolls Atomic Power Laboratory), 2401 River Rd.., Niskayuna, NY. Designed electromechanical control drive (“servoâ€) mechanisms for the naval nuclear propulsion industry. Worked with many motor types including induction motors, permanent magnet motors (“brushless dcâ€), reluctance and magnetic bearings for shipboard applications. Developed numerical tools and methodologies for applications for electromechanical components including motors and generators. Received GE Power Systems award in 1991 for work on three-dimensional numerical electromagnetic methods for Naval Nuclear Propulsion program. Designed CDM’s for S9G (Virginia class submarine) power plant. Wrote a “textbook length†manuscript on electromagnetic design of motors (esp. naval reactor control drive mechanisms). Designed inductors and transformers for shipboard applications, which resulted in about 40% reduction in weight and volume for application to shipboard power supplies. Developed new imaging methods for electrical components (“inverse problemsâ€). Sole inventor of a new method for measuring the vibration energy of magnetic components. SBIR referee for the Navy. (DOE “Q†clearance.)
1984-87: Senior electrical engineer, General Electric Co., Malta, NY. Developed analytical (numerical and mathematical) methods for application to the design of specialized electromagnetic components including electromagnetic launchers, inductors, and rotating machines. (DOD clearance)
1976-84: Electrical engineer, General Electric Co., Corporate Research and Development, Schenectady, NY. Developed new electromagnetic based instrumentation methods for application to the electric power industry.
1976-81: Adjunct Professor, Department of Electrical Engineering, Union College, Schenectady, NY. Taught courses in analog circuits and control systems (“servo mechanismsâ€) with laboratory.

Publications: Approximately 21 technical articles prior to 1987 including a successful text entitled Low Frequency Electromagnetic Design published by Marcel Dekker, Inc. in 1985. Sole author of an article entitled “Multiple Layer Series Connected Winding Design for Minimum Lossesâ€, IEEE Vol. PAS-98, no. 1, 1979. This paper was cited in a research study in Duke University as one of the “most significant†articles pertaining to copper losses in transformers. This report is the1989 IEEE Applied Power Electronics Conference Record, paper no. 3/89/0000-0373.
Additional qualifications: Many years experience in Microsoft products and UNIX operating systems and Cray processing. Fifteen years experience in developing and testing finite element programs for electromagnetic analysis including sinusoidal steady state and transient electromagnetics. Eighteen years working with commercial two- and three-dimensional programs including Vector Fields, Inc., (2-D and 3-D). Significant experience with Ansoft HFSS (high frequency analysis) in applications to “frequency selective surfaces.†Successful design of electromechanical components including permanent magnet machines for control of nuclear reactors. Three dimensional modeling with commercial; programs including PATRAN. Experienced with FORTRAN, C and C++, Matlab with Simulink, and EE “systems programsâ€. Familiar with all types of instrumentation for power flow applications. Expert in all aspects of permanent magnets.
