INDUSTRIAL WORK EXPERIENCE Reverse Chronological Order

ENGINEERING CONSULTING PCES: 6/2004 to Present

Provided a wide variety of services, ranging from design guidance and specification development, root cause

failure analysis, failure forensics, patent research, design testing, as well as other duties. Market areas of designs

varied from military, commercial products, medical devices, aviation systems, industrial designs and controls, and

consumer appliances.

SENIOR DESIGN ENGINEER Powerware / Invensys: 1/2002 to 3/2003

Coordinated with newly formed team merged from the former Powerware 3-phase group and the CATV group to

develop a cost reduced and feature enhanced product upgrade in the 50-160KVA power range. Had become the

sole engineering Lean Design / Black Belt instructor for Powerware.

ENGINEERING MANAGER, CATV UPS GROUP Powerware/Invensys: 1/2000 to 1/2002

Moved to a sister division of Powerware to lead in the role of engineering manager. Have been trained with the

corporate Lean Design Blackbelt / 6 Sigma course, and have implemented the concepts into real life designs

resulting in large savings and increased profit for the company. As manager, have turned around a failing design

group with low morale, and within 18 months have developed a strong functional team with several successful

projects. Have become skilled at fostering team creativity while guiding teams through objective design selection.

Also have performed other management duties such as engineering project management, employment, providing

budgets, team coordination, and other administration responsibilities.

HIGH POWER UPS DESIGN ENGINEER Powerware / Invensys: 6/98 to 12/99

Worked on a product redesign/cost reduction effort for the large UPS group. My major contribution to the design

was the 750KVA power inverter section and gate driver design, with the next step to increase the output capability

to 1MVA, which was tested and passed the requirements. Was able to vastly increase the efficiency (~98%) over

that of existing designs, helping reduce size and cost. Responsible for verifying that the 12-pulse SCR input stage

and the IGBT output stage designs were thermally and electrically sound. Also part of the team responsible for

product qualification testing for UL and other agency tests. On the last project for the group, provided design

assistance for the smaller 20KVA UPS system with the Powerware Canada team.

INDUSTRIAL WORK EXPERIENCE Continued

MOTOR DRIVE DESIGN ENGINEER Eurotherm Drives, Inc.: 9/96 to 6/98

While living in England, developed and helped work into manufacturing a control board upgrade for improving

drive performance and decreasing manufacturing costs, while also improving manufacturability. Also made power

device tests to replace the IGBT s used in the main AC products in the 25HP - 90HP range. These duties were

performed while living in England for one year to aid in releasing the product to manufacturing. After returning to

the US, worked to develop the next generation AC product, which operated in the 220-240VAC and 400-500VAC

range, met all required IEC/CE and UL standards.

MOTOR DRIVE DESIGN ENGINEER - Pacific Scientific/Powertec Division: 10/94 to 8/96

Designed and tested Powertec's new IGBT based drives for industrial brushless DC motors, which ranged from

20HP to 300HP and used resolver feedback from the motor. Directly engineered many subsystems within the

drive design, and selected power components for the inverter stage, capacitor banks, and the control electronics for

each of the different frame sizes and performed measurements and tests to verify design. In November of 1995,

was promoted to the position of Engineering Manager to guide the engineering team through the remainder of the

Millennium product development. The engineering team consists of power electronic engineers, software

engineers, CAD designers, and various technicians. Performed a leading role in the company ISO9000

certification program, by structuring procedures and implementing R&D documentation.

SWITCHING SUPPLY & MOTOR DRIVE DESIGN - Square D Company: 9/92 to 10/94

Worked as part of a team in a joint motor drive development with Telemecanique in France. Was directly

responsible for designing the power and interface board that contained control interface electronics as well as the

flyback switching supplies (Vin

ATV66 drives in the 100HP to 400HP range. Other duties included writing product specifications, manuals,

production documents, qualification tests, and other documentation. Worked closely with the UL, NEMA, CSA,

and IEC standards to develop the product. Wrote and performed qualification tests for the product in the areas of

EMI radiation, voltage isolation, environmental, thermal, application specific, and user abuse endurance.

EDUCATION

MSEE: AUBURN UNIVERSITY, 1992

Researched and designed unique converter topologies to equalize battery charging and maximizing battery life and

co-designing other areas. Studied PWM, resonant, quasi-resonant converter systems and their analyses. Advanced

courses taken include power electronics, digital systems, controls, and electronic design.

As part of the Auburn fellowship requirements, taught and supervised undergraduate labs in areas of computer

architecture, linear analysis and circuit analysis while also assisting teaching faculty. Also performed research

studies in various areas of power electronics.

BEE: AUBURN UNIVERSITY, 1989

During undergraduate studies, researched superconductor load switching using microwaves. Designed, prototyped
