About Us

Our Mission

Tiny Earth is a network of instructors and students focused on crowdsourcing antibiotic discovery from soil.  The mission of the program is two-fold:

First, it seeks to inspire students to pursue careers in science through original laboratory and field research conducted in introductory courses with the potential for global impact.

Second, it aims to address a worldwide health threat—the diminishing supply of effective antibiotics—by tapping into the collective power of many student researchers concurrently tackling the same challenge, living up to its motto “studentsourcing antibiotic discovery.”

Our Roots

Tiny Earth as we know it was launched in June of 2018, but it truly began six years earlier when Jo Handelsman founded a course—then called “Microbes to Molecules”—at Yale University with the goal of addressing both the antibiotic crisis and the shortage of science trainees. In short order, the course grew and became a part of a larger initiative until Handelsman returned to the University of Wisconsin-Madison and launched Tiny Earth in collaboration with its hundreds of partners worldwide.


Our Community

Today nearly 10,000 students are enrolled in some version of the course annually in 41 U.S. states and 14 countries. The program, headquartered at UW-Madison’s Wisconsin Institute for Discovery, is more than just a course: a network of talented students and instructors share research findings, best practices, and enthusiasm for discovery. The name Tiny Earth reflects the program’s global reach, microscopic subjects, and tight-knit community.


Our Ambition

Today we are taking new steps to build and maintain a database of compounds discovered by students, create a chemistry hub to analyze samples centrally , and update the curriculum based on new evaluation tools. Tiny Earth also has new partnerships with the Joint Genome Initiative and the Illumina Corporation to support its scientific mission with free sample sequencing. As our community grows, so do our ambitions. We remain committed to providing excellent and engaging science education and solving the antibiotic crisis.
