PEOPLE + PRODUCTS + POSSIBILITY

Hi, I’m Lily.

I’m a Human Factors Engineer with graduate training in Mechanical Engineering at Tufts, focused on human-centered product development.

I’m especially interested in the point where understanding a user becomes an engineering problem: defining requirements, developing concepts, building prototypes, testing them, and using what we learn to improve the design.

My work spans mechanical design, CAD, fabrication, physical prototyping, ergonomics, usability testing, accessibility, and digital product design.

Whether I’m developing a physical product or a digital interaction, I want the final solution to work technically and work well for the person using it.

OUTSIDE THE WORKSHOP

Beyond Engineering

Nature, travel, music, and time outdoors keep me curious. I enjoy making things and creative projects — finding new ways to look at the world, both inside and outside engineering.
