Conducted a Design of Experiment (DOE) to characterize the sealing process for creating a sterile barrier for the medical devices. The DOE results led to a significant process improvement by widening the operating range, demonstrating that seals could be consistently manufactured with a heating temperature variation of 5% from nominal parameters. Identified a significant manufacturing issue with the packaging component for the device. Through collaborative efforts with the supplier and root cause analysis, NCMRs and RMAs were issued for lots, and corrective measures were established to ensure consistent compliance with the specified requirement and to prevent potential product launch delays. Generated a process validation protocol for the sterile barrier manufacturing process, including operational qualifications (OQ) and performance qualifications (PQ). Collaborated with operators to execute the validation, conducting a process capability analysis to ensure consistent, high-quality results and effectively reduce defective parts per million Designed and implemented a manufacturing fixture to address operator fatigue issues in an assembly process. This fixture improved the manufacturing process by alleviating the physical strain on operators' fingers, ensuring improved efficiency and reduced fatigue-related issues. Conducted a thorough characterization of the catheter’s outer jacket material by developing a series of test methods. Results provided crucial insight into the material properties, identifying a 25% increase in wall thickness after lamination across all lots, and a negative correlation between wall thickness and material elongation. Performed time studies on different manufacturing processes and supplied the collected data to a senior engineer. This data was then used to create an approximation for the total build time for a device. Developed a test method needed for in-process monitoring, referencing ASTM F88.

Performed end-to-end product development tasks encompassing the conceptualization and realization of a test fixture, alongside conducting mechanical tests to evaluate various functions of the medical device.

Utilized COMSOL Multiphysics FEA simulations to analyze BioMEMS devices, while also collecting empirical data on the progression of liquids on nitrocellulose membranes, under the guidance of Dr. Lawrence Kulinsky.

Developed a MATLAB algorithm to assess the impact of charging electric vehicles during peak hours on the lifespan of a transformer.

Managed a 30-member team to oversee the initiation, planning, design, manufacturing, and testing phases of a functional solar-powered race car.

Supervised a three-member team responsible for designing the powertrain and power flow system of the vehicle.

Generated CAD models of a test bench specifically designed for conducting tests on a 96 Volt motor.

Tested and implemented control sequences in industrialized buildings to minimize energy costs from HVAC utilities.
