As a member of the Human Factors Engineering team at Marshall Space Flight Center, I worked with master carpenters, applied psychologists, systems engineers, industrial designers and interns.
My responsibilities included: designing data capture systems for user testing, managing scaffold design and installation in a 30-ft tall mockup, conducting contextual interviews at Kennedy Space Center and facilitating a concept pipeline for Ground Support Equipment.

Performance Analysis & Design Demonstrator (P.A.D.D.) of Ares I Upper Stage Instrument Unit.
Simulating reach-in tasks to assess visibility and tool clearance.
Notable factors in Human Systems Integration: functional limitations while wearing protective equipment, strict avoidance of foreign object debris, and standards for ground crew safety.
Mockups represented ground crew access zones: Instrument Unit, Interstage, bottom of Upper Stage including J-2X Engine, and Forward Frustum.
I attended scaffold safety and fall protection Train-the-Trainer courses to certify teammates and design scaffolding configurations.

Our team carried out an extensive design development process with several internal and external stakeholders, and I managed key phases of concept selection and presentation.
This demonstrator of the Upper Stage Thrust Cone contains part mockups that utilized: aluminum fabrication, building construction expertise, fiberglass, wood turning, 3D printing (both onsite and through a high school collaboration), pool noodles, foam core and large-format graphics.
With the phasing out of the Space Shuttle program, I proposed that our design team in Huntsville (MSFC) learn directly from current ground crew in Cape Canaveral (KSC). These insights were incorporated into concurrent designs of internal access Ground Support Equipment. (MSFC: Marshall Space Flight Center, KSC: Kennedy Space Center)
Supported by new research funding, I managed a small team of contractors as we developed a database of ground crew tasks. We created mockups with minimal surface obstructions, designed the research protocol, captured motions for typical scenarios, and delivered a database tool for designers at multiple NASA centers.
