Industrial Experience
Electro Standards Laboratory, Cranston RI
Position: Mechanical Design Engineer. Duration: May–September 2020
Production: Designed and CNC machined enclosures for switching, data acquisition, and control products. Constructed detailed drawings for quality assurance inspection and cable management assemblage.
R&D: Mechanical design and heat transfer analysis of energy storage cabinets containing Lithium-ion Super Capacitors.
Gerber Technology, Tolland CT
Position: Summer Mechanical Engineering Internship. Duration: June–August 2019
Coordinated with a senior principal engineer on a solution to prevent overlay plastic film from jamming on an automated cutting table.
Assisted in the design and analysis of a mechanism to apply constant tension on the film; ultimately pulling it over the jam location. Proposed and prototyped an electrical approach using a current limiting circuit with current sense feedback using shunt resistor.
