Making health and safety easier to reach.

From an ammonia-responsive food-spoilage patch designed to cost about twenty cents to health-information delivery across twenty schools, I build around the people a system is supposed to serve.

Who I am

I keep returning to one question: who gets to use the solution?

My work began in the lab, but it rarely stays there. A food-spoilage sensor led me to affordability and interpretation. Public-health work pushed me toward information access.

Student government taught me that durable change often depends on the structure around a problem—not only the person facing it. Across each field, access is the design brief.

Selected work

Three ways I build for access.

Each project starts with a person excluded by cost, information, or process—and asks what would have to change for the system to include them.

Low-cost sensing

Making spoilage visible.

An agarose-anthocyanin hydrogel patch turns invisible ammonia into a four-stage color signal without specialized equipment.

Public health

Making information travel.

KMLA HOSA grew from five members into a recurring service and health-information system reaching schools across Gangwon Province.

As Student Legislative Council president, I treated livestreams, next-morning minutes, and clear voting thresholds as civic infrastructure.
