Zahin H Ritee

Mechanical Engineering Graduate Student & GEM Fellow @Columbia University

Ozone Park, NY

ABOUT ME

I’m Zahin Ritee, a dual-degree graduate in Mechanical Engineering (Columbia University) and Physics (Adelphi University), now pursuing my M.S. in Mechanical Engineering at Columbia as a GEM Fellow. I bring expertise in Optics with hands-on experience in lasers and optical fibers, mechanical design, manufacturing, and controls, with hands-on experience in CAD, CNC machining, 3D printing, and system integration. Beyond engineering, I’m passionate about singing, which inspires the creativity and focus I bring to solving complex, real-world problems.
