Dr. Oudrari has a wide experience working for large scale NASA and NOAA projects and programs, multi-organizational and multi-national initiatives, interacting closely with vendors, subcontractors and multiple government agencies, and development and delivery of professional services offerings.

    Dr. Oudrari combines strong analytical, leadership, and communication skills with experience in team building and high performance teams. Highly skilled in motivating and mentoring staff to achieve objectives. Excellent organizational experience guiding strategy development, and implementing process improvements. He has a strong communication abilities exhibited through presentations at major program reviews and milestone meetings.

    Positions/Employment

    8 / 2009 - Present

    Chief Engineer

    Sigma Space Corporation, Lanham, MD Satellite Systems Engineering - Sensor Calibration and Characterization
    Coordinating a high performance team of scientists to calibrate and characterize a series of space-based Earth Observation sensors on-board the NASA/NOAA Suomi-NPP and JPSS programs.

    My responsibilities include the coordination of large team of scientists and experts to provide an independent performance verification and validation of one of the key instruments on S-NPP and JPSS spacecrafts, the Visible Infrared Imaging Radiometer Suite (VIIRS). I'm the NASA representative leading the planning, and assigning roles and responsibilities, as well as conducting continuous interactions with the sensor and spacecraft contractors and other government teams. I'm also supporting all major reviews and milestone, and reporting on the sensor development status to the project and program management.
