Significant Projects at Marshall Space Flight Center

Developed the natural environment definition, requirements, and reporting for the Constellation architecture

Performed ground crew duties for the Stardust re-entry from Battle Mountain, Nevada

Developed the five radiation environments for the new “Natural Environment Design Document,” which baselines environment requirements for the Crew Launch Vehicle, Crew Exploration Vehicle, and Lunar Lander.

Developed a technique for estimation of galactic cosmic radiation through complex structures on the lunar surface.

Provided space weather support for the Demonstration of Autonomous Rendezvous Technology (DART) flight demonstration project.

Performed as radiation environment sub-task lead

Assisted in the Leonid Observation Campaign in Tenerife, Canary Islands, Spain.

Assisted in the STS-107 investigation

Assisted in the testing, alteration of design, and re-testing for qualification of four DC/DC converters for the Environment Control and Life Support System (ECLSS) for the International Space Station.

Performed the qualification of electronics parts for the radiation environment of the Propulsive Small Expendable Deployment System (ProSEDS) mission

Developed a radiation test program and methodology which was used for the testing of the Solar Sail, Orbiting Wide Angle Lens, the Hubble Space Telescope passive multi-layer insulation, and silicon and diamond structures for Micro Electro Mechanical Systems (MEMS).

Created a 3-D geometric radiation model of the Node 2 segment of the International Space Station using the NOVICE code.

Reviewed the radiation environment models for the Manned Mars Exploration mission, the Mars Assent Vehicle, the Space Solar Power Generation Unit, and the Next Generation Space Telescope.

Developed the Boilerplate Radiation Environment Document and the Alpha Particle Design Environment for NASA Marshall Space Flight Center.

Assisted in electronics parts review and qualification for the Chandra Space Telescope, as well as considerable work in developing explanations for variations in the natural space environment during flight.

Developed a database of radiation tested parts for use in design of spacecraft.
