In this episode, Stephanie Feuer and Mindy Yang of the World Taste & Smell Association speak with Dr. Derek Toomre, a Yale scientist, Professor, and inventor whose work helped transform smell testing from an inaccessible clinical tool into a global public-health innovation.

Derek’s company, U-Smell-It, created the world’s first low-cost, open-source smell-testing kit, designed to democratize olfactory diagnostics for both clinical and community use. What began as a rapid response to COVID-19 has become a vital resource for sensory health, research, and education — empowering anyone to test their sense of smell at home.

We explore how U-Smell-It works, why smell is such a powerful indicator of health, and how tools like this are changing the way we understand human perception.

You can now order U-Smell-It directly from the World Taste & Smell Association at TasteAndSmell.org.
