At Johnson & Johnson, I contributed to three primary areas: CAD design, fixture development, and simulation.Created over 50 CAD drawings with hundreds of revisions to document and improve critical capital equipment.Streamlined updates across teams by adhering to the company's rigorous drafting standards.Managed over 30 design files in the Product Lifecycle Management (PLM) system, becoming a go-to resource for troubleshooting and optimizing workflows.Supported colleagues by resolving PLM-related issues, further enhancing team efficiency.Developed a precision fixture to support testing for a long-standing alignment issue in arthroscopic camera heads.Led the project from concept to a fully machined product in just two months while collaborating with cross-functional teams.Delivered a reliable tool that quantified the alignment issue, providing a foundation for future design improvements.Refined the design through iterative feedback to ensure it met all testing requirements.Conducted simulations to model mechanical interactions, such as a burr cutting through a bone block, using ANSYS and the LS-DYNA solver.Solved key challenges, including instability caused by a miscalculated center of mass, through independent problem-solving.Directed weekly meetings of 3–6 engineers from England, Ohio, and Massachusetts to gather input and refine models.Produced a technical report summarizing tasks, unresolved issues, and next steps, enabling the continuation of simulation development.

At Boston Children's Hospital, I developed a calibration process for a custom triaxial accelerometer, magnetometer, and gyroscope designed to operate in a 3 Tesla magnetic field.The system aimed to track patient head motion during MRI scans and correct movement artifacts to improve imaging quality.I carried out the following: conducted testing of linear calibration techniques, reviewed over a dozen research papers, and evaluated alternative approaches.When the linear techniques failed completely to provide usable results, I identified a nonlinear calibration method as the correct solution.This method relied on ensuring the voltage vector norm equaled 1 G for acceleration, the magnetic field norm equaled 3 Tesla, and the two vectors were orthogonal, consistent with MRI calibration standards.I completed testing of the nonlinear calibration process, achieving results that validated its effectiveness and supported further research and development.I collaborated with another intern to document the workflow in a comprehensive technical report, detailing the design process, calibration techniques, challenges encountered, and recommendations for improvement.I concluded the project by presenting our findings to the research group, highlighting the testing results and the potential for quality improvements in MRI motion correction.This experience enhanced my skills in design, process development, testing, and technical writing while contributing to advancements in medical imaging technology.
