OBJECTIVE
To obtain a position in electrical/electronic systems operation, programming, or administration with opportunities for advancement.

EXPERIENCE
· 8 years in the Naval Nuclear Power Program (September 1977-October 1985). Primarily trained as an electrical operator. This involved the control, monitoring, and repair of various types of electrical generation/conversion equipment and their associated electronic control systems, electrical distribution equipment, atmosphere control equipment, and propulsion plant/ship systems auxiliary equipment. During this time I held a secret security clearance.

· 5 1/2 years assigned to the USS Ohio-SSBN 726 (first Trident class ballistic missile submarine). Participated in initial ship, reactor plant, and propulsion plant construction and testing (January 1980-August 1982). Completed 5 operational patrol cycles (August 1982-May 1985). Performed the duties of a divisional level manager during both administrative and overhaul/at sea periods (January 1984-May 1985).

· Assigned to the USS Pargo-SSN 650 (May 1985-October 1985). Worked as the administrative assistant to the engineering department head. The ship was undergoing a non-refueling overhaul at the Puget Sound Naval Shipyard, Bremerton, Washington.

· Employed as an Array Operator for the National Radio Astronomy Observatory, Very Large Array (VLA) facility on the Plains of San Augustin, New Mexico (March 1986-November 1989). The VLA is a 27 element radio telescope interferometer which is controlled from a control building situated near the center of three 22km long arms along which the 25m diameter antennas are positioned. The Array Operator controls and monitors the computer systems used to control the antennas and site auxiliary systems, monitors and takes corrective action for equipment malfunctions, modifies observing programs as required, maintains observing logs, initiates maintenance callouts, controls "traffic" of maintenance personnel on the array, and is responsible for personnel and equipment safety. In addition to the routine astronomical observing the VLA antennas were arrayed with the National Aeronautics and Space Administration's (NASA) Deep Space Network (DSN) antennas located at Goldstone, California to assist NASA in the reception of image data from the Voyager 2 spacecraft as it flew by the planet Neptune in August 1989.

· Employed as the Chief Operator for the National Radio Astronomy Observatory, Very Long Baseline Array (VLBA) project (December 1989-September 1993). The VLBA is a 10 element radio telescope interferometer. The 25m diameter antennas are controlled remotely from the Array Operations Center in Socorro, New Mexico. The antennas are spread out across the United States from St. Croix in the U.S. Virgin Islands to Mauna Kea, Hawaii. The Chief Operator is responsible for the supervision of the Array and Correlator Operators and the management, administration, planning, and coordination of the daily, as well long range array activities. The time period of this job covered the main construction phase of the VLBA when the complement of antennas went from two operational antennas to all ten. In addition to normal managerial duties this time period necessitated the establishment of all operating procedures, test procedures, and a preventative maintenance system for remote antenna operations. During this time I also designed, coded, and implemented several major, mission critical software programs including the display systems used by the control room operators for monitoring antenna systems, the computer to computer communication system used to command and control the ten independent antennas as a unified array, an information retrieval system for on-line operating documentation, and a distributed database system capable of tracking shipments of recording tapes containing scientific data to and from radio astronomy facilities around the world. These programs are still in use by the observatory.

· Traveling in the Western Pacific (September 1993-February 1998). During this time period I lived aboard and crewed on several sailing yachts in and around the islands of the countries of Indonesia, Malaysia and the Philippines. Visits were also made to Hong Kong and the island of Guam. The last two years of this time was primarily spent living with a local family in a small fishing village in the province of Negros Oriental in the Philippines.

· Employed as an Array Operator for the National Radio Astronomy Observatory, Very Long Baseline Array (VLBA) project in Socorro, New Mexico (February 1998-July 2000). The Array Operator controls and monitors the computer systems used to receive and display the continuous stream of monitor data sent by each of the 10 radio telescope antenna station computers, controls the antennas and site auxiliary systems by issuing commands from the array central control computer, monitors and takes corrective action for equipment malfunctions, modifies observing programs as required, maintains observing logs, initiates maintenance callouts, monitors weather conditions at each of the antenna sites, and is responsible for equipment safety. Rewrote and updated the monitoring and control software that I wrote as the Chief Operator.

· Employed as a Seismological Software Engineer/Scientist for the Incorporated Research Institutions for Seismology (IRIS) Program for Array Seismic Studies of the Continental Lithosphere (PASSCAL).  The PASSCAL Instrument Center (PIC) develops software, and maintains portable hardware used for monitoring both artificial/active source, and naturally occurring seismic activity.
