PROFESSIONAL BACKGROUND

Companies/Vendors: Lockheed-Martin, Georgia Institute of Technology, Boeing, Rockwell, TRW, IBM, Thiokol, Grumman, and others.

  • Awarded NASA’s "Group Achievement Award" for successfully enhancing, implementing, testing, and analyzing new Space Shuttle Solid Rocket Booster design after Challenger accident.
  • 4500% cost savings and 8900% increase in productivity through researching and developing a new testing process for Space Shuttle thermal tile bond verification.
  • Recognized for Innovative Research and Development for creating research software used for testing the accuracy of the Mars Observer Probe Flight Software.
  • Help to improve space shuttle flight safety and performance by participating in redesign of solid rocket booster igniter and field joint protection system.
  • Used Piezoelectric and PVDF sensors and actuators for structural vibration suppression and anomaly detection in various aerospace structures (e.g., Fighter jet vertical tails, space shuttle tile debonds).
  • Participated as a key team member to design and test a new integrated work control system for the space shuttle program.
PROFESSIONAL PROFILE
  • Results-oriented professional employing more than 10 years of progressive accomplishments in engineering.
  • Disciplined self-starter, with the unique ability to comprehend complex, and unrelated information and digest into workable terms.
  • Proven leader, providing the momentum required to unit diverse groups toward a common goal.
  • Team player, able to plan, organize and complete projects on time and within budget.
  • Catalytic problem-solving leader, who thinks logically, values creativity and cares about people.
EXPERIENCE
  • Georgia Institute of Technology, Atlanta, GA
    Research Assistant 1997 - present

    Perform structural dynamic testing on various Aerospace structures for anomaly detection and vibration suppression. Anomaly detection is performed by vibrating the test structure and characterizing the response in the frequency domain. The vibration suppression is performed using robust control and piezoceramic based actuators. Conducted research in stress distribution in adaptive structures with active damping using analytical, experimental and numerical methods. Current research is in the area of compact hybrid piezoceramic based actuators for use in robotics, aircraft and spacecraft.

    Extended Tk/tcl base installation to include tclX, blt, pvm, and itcl so that the interpreter could be used as a configurable web-based server. This server has been used to demonstrate a functional method for providing design-related services on the web. This work included the development of tcl functions to process prediction profiles for doing robust design. This included coupling additional graphics programs, such as ImageMagick and Gnuplot, into the server process.

    Instruct classes in ABAQUS, ANSYS, and Matlab for the College of Engineering. These classes are introductions to these applications that include both 2-D and 3-D modeling. The students are composed of undergraduate and graduate students as well as faculty from all engineering departments (Aerospace, Mechanical, Civil, Electrical, etc..). I currently hold the position of chief finite element applications and Matlab contact for the College of Engineering at Georgia Tech.
