Our Network

Tiny Earth is a global network of students and instructors dedicated to discovering new antibiotics from soil and creating engaging laboratory coursework.

Today, tens of thousands of students are enrolled annually in some version of the course initially chartered at Yale University in 2012 by Jo Handelsman; the network spans 23 countries, 44 United States, Puerto Rico, and Washington, DC. The program, headquartered at UW-Madison’s Wisconsin Institute for Discovery, is more than just a class: a network of students and over 700 instructors share research findings, best practices, and enthusiasm for discovery, including at the community’s annual symposium. The name Tiny Earth reflects the program’s global reach, microscopic subjects, and tight-knit community. (Map is interactive. You may zoom and click on a pin to discover our various partners.)
