Hello! I’m Katelyn Guo. An engineer and designer interested in how objects move, feel, and connect with people.

I'm a mechanical engineering student at Brown, where I design and fabricate things ranging from carbon fiber aerodynamic components for our Formula SAE race car to medical devices developed alongside surgeons. I like the full process — early concepts, iterations, the moment something finally works the way it's supposed to.

I'm also drawn to projects that ask different questions. Through wearable design and fashion, I think about how structure and material move with the body, and how design can shape the experience of the person inside it. Those questions don't feel separate from engineering to me. They feel like the interesting part.

Outside of projects, I'm usually thrifting (at the bins!), at a K-pop concert, playing tennis, or making silly TikToks.

I'm looking for roles in product design and development where I can build across disciplines and make things that feel as good as they function.
