HPS is a club at UCSD which designs and builds a working, human powered submarine. Every two years, they take the submarine to compete globally in Maryland. Owen is a team lead of the Hull team, which is responsible for constructing a strong, light, and hydrodynamic hull; a member of Dive team, open water dive certified in order to perform underwater tests of the submarine and be a safety diver during competition; and a member of Drivetrain team to create a powerful, reliable propeller system to power the submarine. The submarine must be kept stable, secure, and safe because it will hold a person during the competition.
The team competed at the 18th International Submarine Races with their one man propellor submarine Calypso Mod 1 at the Naval Surface Warfare Center, Carderock in Bethesda, MD.

(Right) The team was awarded "Best Design Outline" for their design report and presentation at the race.
Owen is a lead of the Hull team, leading a team of 15 students from diverse backgrounds and majors to design, analyze, fabricate and test the hull of the submarine.
Owen has already successfully led the Hull team through the development of the hull of Calypso Mod. 1 for the ISR 18 competition and is currently leading the development of the next submarine hull to compete in 2026.

Owen is a member of the dive team and is a safety diver to help perform underwater tests of the submarine and ensure safety during the competition race.

(Left) Image of the team at a STEM fair which we tabled at. We performed demonstrations and explained our designs to inspire Preuss School students to pursue STEM.
(Right) A work day on creating a test stand for our drivetrain. Creating a mount for the gearbox and pedals which we could use while pedaling to measure our power output from the system.
(Left) Using a CNC mill to create positive molds for the submarine's viewports which will be vacuum formed with PETG plastic.
(Right) Performing adjustments on the submarine's cart. Updating it so that it is more maneuverable and smaller to fit in tighter spaces. This required a redesign, and sheet metal work.
