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 acquisition, analysis, and presentation of experiments. Technical responsibilities included: • 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 included creating a parametric FE model that simulates existing underbody blast experiments, as well as tissue testing to obtain more accurate material properties.

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 variables and test conditions. Presented abstract at the BYU Emerging Ideas in Biomedical Research Conference. Technical responsibilities included:• 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 step of the R&D process as the only fully dedicated member to this specific project. Technical responsibilities included: • 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
