I have worked with hardware that withstood the extreme depths of the ocean, the hard vacuum and radiation environment of outer space, to foreign battlefields�

I have always loved a challenge.I am results oriented; I would rather push ahead boldly and get the job done.Beginning as a young child, I stood awe-struck as I watched the Echo balloon satellite pass overhead. I grew up as an avid fan for space exploration. I was fortunate to meet with Dr. Arthur C. Clarke, Dr. Werner von Braun, Neil Armstrong, among many other famous aerospace professionals and authors that inspired me to seek a career in aerospace. I was later in life to work on the Delta-4 launch vehicle pad optical communications infrastructure.

I studied Physics and Mathematics at Indiana University and specialized in Optics. I took a position with NASA at the Johnson Space Center in May 1980 where I served as Project Engineer for optical experiments and computer payloads on the first four missions of the space shuttle.I left NASA in 1981 to join private industry, where I designed the first optical fiber cable for geophysical exploration systems.  Over the next 16 years as a cable engineer, I gained detailed knowledge of practical applied physics.

I built detailed SPICE models of cables for electrical and optical performance, stress/strain/rotation mechanical performance, and developed equations for macroscopic system performance (cable buoyancy, center of gravity, center of mass, moment of inertia). I developed an expert system (50,000 lines of FORTRAN, main program and 22 subroutines) for the design of working cables. The expert system predicted power, coaxial, twin axial, fiber optic, plus aramid and steel strength member element performance. Another subroutine predicted theoretical cable performance in the areas of tensile strength, rotation, electrical parameters, and optical performance.

At Litton Corporation (1984), I served in the dual role of technical liaison and designer on the first undersea All Optic Towed Array (AOTA).I designed a fiber optic lead-in cable and fiber optic acoustic sensors, analyzed complex optical system performance using FORTRAN, assisted in the development, alignment and calibration methods for infra-red hardware, and performed acceptance testing of hardware using accepted industry test standards and specifications. I also reverse engineered a microwave system to accurately measure optical fiber path length; and another system to predict power loss from bends using a test calibrator for the optical fiber AOTA tow cable lead-in section.

I later applied my detailed knowledge of materials engineering for cables to invent three space tether systems: satellite delivery, sub-orbital package delivery, and orbital debris removal.

I served as lead optical fiber engineer at Boeing on the Delta-4 EELV (Evolved Expendable Launch Vehicle) for the Eastern and Western Range Launch Pad construction. I designed and installed the optical fiber cable, connectors, patch panels, video system, associated hardware, and RF-over-optical fiber systems which the Delta-4 Launch Control System video and data network rides upon. The project was completed under budget and ahead of schedule, as were 95% of the projects during my career.

I served on two NASA/Contractor "Tiger Teams" analyzing, testing, and resolving an optical fiber (ESD related) design flaw for a space station module on orbit (US Lab). Our team developed methods to test and repair optical fiber cable already on orbit. I conducted environmental stress tests (Thermal Cycle, Vibration, Shock, Material Compatibility, Outgas, Radiation, and Optical Performance) for the Fiber Optic Fault Finder Device (FOFFD) optical fiber test equipment payload (Boeing) for Mission 2A.2B (Sep 2000) to International Space Station.

I teamed with others at the 45th space wing to upgrade the network communications for the launch infrastructure at Cape Canaveral AFS. I served as analyst, defined the Network, Instrumentation, RF/Radar engineering efforts and upgrades for the 45th Space Wing (USAF). I verified and validated the designs and upgrades to the communications infrastructure for the EELV launch pad ER interfaces (Atlas-V/Delta-4). I oversaw the installation and test of the video hardware upgrade for the EELV High Definition TV. I provided technical oversight to the validation/verification testing of multiple launch vehicle simulations for the network hardware upgrades.

On the Admiralty Board of Space Frontier Operations (www.sfo.org), I wrote the Space Exploration Base (SEB) Concept of Operations document. The SEB references a 1600 foot diameter, one-g artificial gravity space station designed for permanent presence of a crew of 300 in medium earth orbit. The paper was presented at the 2004 Space Congress, Cocoa Beach, Florida.I also attended the Space Visions 2004 conference in Cambridge, Mass in late 2004, where I met Michael Laine of Liftport and was asked to contribute a chapter on system deployment to the 2006 Liftport, Inc book on the Space Elevator:

LiftPort: Opening Space To Everyone

I worked closely with the RFID re-engineering team as the subject matter expert for PM J-AIT (product manager Joint Automated Identification Technologies) in RF/satellite communications between 2006-2009. I wrote the test methods and executed the testing for the establishment of baseline metrics for active RFID: the ANSI-256 to ISO 18000-7 waveform migration project. I captured test metrics for tags at rest and in motion which were used to write the migration standard for the RFID manufacturers.

 

I served as technical oversight to the US Marines in support of a microwave network installation in Bahrain for the Bahrain Defense Force (2009). I provided the channelization plan and validated the system interfaces for the voice and data circuits. In my personal life, I support global engineering efforts as a team member of the Committee for Middle East Electricity for Peace.
