As a Manufacturing Engineering Intern at Johnson & Johnson Vision, I contributed to high volume production operations in a facility responsible for producing over 500 million contact lenses annually. My primary project focused on minimizing downtime and contamination risk by analyzing exhaust hood efficiency through SolidWorks flow simulation and optimizing laminar airflow, turbulence, and recirculation patterns. To ensure simulation accuracy, I regularly collected real-time measurements on the manufacturing line, allowing the modeled system to closely reflect actual operating conditions. I redesigned multiple system components and evaluated 97 possible design configurations, ultimately presenting recommendations to executives and manufacturing leadership that balanced system performance, manufacturability, and compliance. In addition, I conducted package integrity testing to verify proper heat seals in an FDA- and European Union Medical Device Regulation (EUDMR) regulated facility, ensuring quality standards were consistently met. Beyond technical work, I participated in lunch and learn sessions with various departments, gaining valuable insight into the broader scope of engineering and manufacturing operations within the organization. This experience strengthened my skills in computational fluid dynamics, design optimization, and technical communication while providing exposure to the demands of engineering in a highly regulated medical device manufacturing environment.
