Electrical Engineer
The Dynamic Fault Detection Chassis (DFDC) was an upgrade project that was assigned to me. My responsibility was to design circuitry that reduced the flux voltage offset. Because of this design and modifications to the existing circuit, I was able to significantly reduce input offset voltages, giving me the ability within the chassis to lower threshold voltages well below the maximum limits. I presented this paper at the Particle Accelerator Conference in New Mexico and published my work. Another project that I was the lead engineer on was the High Voltage Converter Modulator (HVCM) Water Panel upgrade. It was my responsibility to redesign the HVCM water panel Box to allow a more efficient way of determining and isolating faults.

EXPERIENCE
01/06 to 03/12
Electrical Engineer/Project Manager
Oak Ridge National Laboratory Spallation Neutron Source Oak Ridge, TN
Design and fabricate dc magnet power supplies, pulsed magnet power supplies, pulsed Klystron modulator systems, and AC power distribution systems. Specify and validate acceptance test plans for dc magnet power supplies, pulsed magnet power supplies, pulsed Klystron modulator systems, and AC power distribution systems. Write installation, repair and maintenance procedures for SNS electrical systems. Performs safety analysis, designs/specifies safety circuits and interlocks. Design analog and digital circuit for low level controllers, develop and support existing PLC code to control modulator systems. I was a Project Manager over several Accelerator improvement projects (AIP’s). For this particular project I was the principal design Engineer that managed the entire project from conception to final installation, I defined the scope; I put together all cost associated with software, installation, test, procurement, fabrication, integration as well as labor cost necessary for the software control engineer, technicians, research mechanics, and vendors. Microsoft Office Project was the program I used to create the schedule; I collaborated with department heads once all data was compiled. A Work Breakdown Structure (WBS) was created, as well as the WBS activity resources units and cost. Once the AIP package was complete, I presented it by Power Point presentation to Department Of Energy (DOE) committee for approval. The DOE approved the AIP and released the funds. The project was completed on time and under budget.
11/04 to 09/05 Platform Engineer
Applied Biosystem Pleasanton, CA
Repair five stage spotters Qarray2, and Beckman FX’s machines. Troubleshoot servo boards, sensors for safety interlocks and controller boards to the component level. Work with engineers in prototype new product lines.
5/00 to 1/06
Electronics Engineer
Mize Enterprises Oakland, CA
Assist engineers in the Design of DSP board. Prototype PCB using schematic capture software, for three axis-engraving tables. Implemented ECO’s to PCB due to obsolete parts. Troubleshoot PC boards to the component level using various types of electronic equipment. I maintained inventory to ensure parts availability.
3/92 to 5/2000
Associate Engineer Integrated Motions Inc. Berkeley, CA
Assist engineers in designing analog and digital circuits, for motion control devices. The analog circuits designed were circuits that used PWM for inputs to H-bridges, to drive current and voltages to the motor. Fast switching power supplies were used, buck converters to regulate the voltage from +48 volts down to + 5 volts, boost converters were used to increase the voltage to +12 volts to supply voltage to the DAC’s. The Zero Force Robot used H-bridges which consisted of FET’s. A failure analysis was performed by me which led me to conclude that component matching was critical when using PWM. Half bridge and full bridge DC- DC converters were used to design and manufacture a five- stage amplifier controller for a five-axis DNA micro array spotter table. I pro...
