    CV

    Education:  B.S. Aerospace Engineering – University of Colorado, Boulder 1988

     

    Clearances: Current TS / SCI / SSBI

     

    Work Experience:

     

    2008 – 2012  : Comtech AeroAstro, Littleton, CO

                Modeling and Simulations / Principal Systems Engineer

     

    • Mission Analysis: Responsible for design, analysis and performance evaluation of various small satellite systems.  Used STK/Matlab to perform various parametric trade studies, analyze orbital events and optimize vehicle design configurations to support proposal and design efforts. Typical examples:

     

    • Satellite eclipse, beta-angle analysis, and solar angles of incidence
    • Optimal placement and orientation of star-trackers
    • Orbit maintenance, station-keeping maneuvers and propellant budgets
    • Orbital decay and de-orbit burn requirements
    • Constellation design with coverage and access requirements
    • Space radiation environment analysis
    • Technical animations to support attitude, thermal, power and mission analysis

     

     

    1999 – 2008  : Lockheed Martin, Denver, CO – Advanced Surveillance & Reconnaissance Programs

                  Modeling and Simulations / Mission Analyst

    • Long term orbit propagation and perturbation effects
    • Sensor placement, blockage, constraints and collection optimization

                                             

    • Simulation & Modeling: Created 3-D visualizations of proposed advanced classified satellite system concepts and architectures using Satellite Tool Kit.  These technically accurate scenarios/visualizations were used to support various proposals, IRADs, and customer demonstrations to help to sell new programs, keep existing programs sold, support various trade-studies and parametric analyses, and to elucidate complex geometric spacecraft scenarios to our customers.  Typical examples:

     

    • Launch, orbit-insertion, station-keeping maneuvers, housekeeping maneuvers, attitude verification, deployment, satellite systems check-out
    • Satellite constellation phasing and build-up strategies
    • Satellite articulations (solar-panels, antennas, payload gimballing)
