As a member of NASA's Occupant Protection team at Johnson Space Center, I perform biomechanical research and analysis to study the loads and accelerations sustained during all phases of spaceflight to protect astronauts and other occupants.

Charlottesville, Virginia Area

• Worked as project manager for PMHS cadaveric working group at UVA as part of the U.S. Army-contracted multi-institutional WIAMan Underbody Blast program. This included experimental planning, fixture design, data.
• Creation and upkeep of technical documents to guide all steps of experiments
• CAD (SolidWorks) design and adaptation of high-energy test fixtures
• Cadaveric preparation, custom instrumentation, and post-test dissection in Biosafety Level-II laboratory
• Experimental data collection using multi-channel data acquisition systems (DTS SlicePro), high-speed video analysis systems (NAC GX1), CMM (Romer), and motion capture support (VICON)
• Data analysis (Mimics/3-Matic, SliceWare, MATLAB) Thesis research included adapting the pelvis portion of an automobile full-body finite-element (FE) model for high-rate, underbody blast rates and conditions. This.

Provo, Utah

• Investigated use of carbon nanotube (CNT) composites as antibacterial coatings for stainless steel biomedical implants. Performed hundreds of experiments using various equipment to determine effects of different input.
• Design of new experiments to test adhesion, hardness, and antibacterial effectiveness of CNT composites
• Prepare specimens using electron-beam and thermal evaporation (thin film deposition) and conduct experiments using a lab furnace
• Analyze repeatability and quality of samples using scanning electron microscopy (SEM)

Provo, UT

• Worked as part of a small team of mechanical and electrical engineers to modify and redesign an electrical generator for downhole drilling equipment utilizing patented synthetic diamond bearings. Participated in each.
• Design and create test equipment using modeling software (Pro-E/Creo) and machining equipment (CNC Mill and manual lathe)
• Create detailed drawings and work with in-house machine shop to produce high-precision parts
• Assemble prototypes and operate custom flow loop test equipment to simulate downhole behavior and evaluate performance and efficiency of generator design
• Work with local 3D Printing company to supply custom parts for generator
• Create detailed assembly instructions and SOPs for electrical generator

Hebron, KY

• Worked under chief engineer to assist in boosting efficiency of growing rubber and plastic plant providing automotive parts to global automotive companies. Technical responsibilities included:
• Perform time studies to gauge accuracy of cycle times for rubber-metal presses
• Investigate inaccuracies and propose actions to fix inaccuracies
• Perform design of experiment to troubleshoot failure of assembly process
• Assisted in design of experiment and its execution to troubleshoot failure in part assembly process.

Erlanger, KY

• Assisted company management and sales engineers in testing new water disinfection systems and creating detailed water disinfection layout plans for customers. Technical responsibilities included:
• Create, modify, and edit engineering drawings (AutoCAD) for water disinfection equipment
• Design and create test equipment and conduct daily tests for novel water disinfection system
• Write and modify operation, maintenance, and instruction manuals
