About

I’m an ocean engineering student at Florida Tech who likes building things that have to survive in the water. I work as a research assistant on Navy-funded composite repair and underwater glider projects, and as an engineering intern at ISensys designing subsea enclosures. Outside class I build custom fishing rods and 3D print scale outboard motors. I’m looking for internships where I can work on marine systems from CAD through water testing.

  • B.S. Ocean Engineering, Florida Tech, expected 2028
  • GPA 3.62
  • Dean’s List, two semesters
  • ASME member
