SEAS Racing Team

I have been a part of Harvard’s SEAS racing team for two years. We are building a fuel-efficient vehicle to compete in the SAE Super-mileage Competition. Last year, I designed and manufactured the rear wheel and transmission to minimize power loss. In June 2018, we placed the highest of any first-year teams. As President of the team, I have handled administrative duties such as scheduling, budgeting, and complying with regulations. From machining to carbon fiber manufacturing, I am working hard to engineer our race car to be fast and fuel efficient.

ES51 Robot Competition

ES51: Computer Aided Machine Design focuses on the design and construction of mechanical and electromechanical devices. I learned engineering graphics, sketching, dimensioning, tolerancing, materials selection, structural design, and the necessity of precision in design and manufacturing. Our team designed and manufactured a robot that won 2nd place in the class competition.
