Our Purpose and Mission

Since 2017, Princeton Environmental Ideathon (PEID) is an all-expenses paid, application-based interdisciplinary design competition for addressing our socio-environmental challenges. The goal of PEID is to bring students of interdisciplinary backgrounds together to begin to solve our most pressing environmental issues. PEID allows students to explore their creativity, learn more about environmental problems and solutions, and network with leaders in the field.

PEID offers an immersion in understanding-centered design thinking as the process by which individuals of vastly different backgrounds and disciplines can collaborate swiftly and efficiently. Ideathoners are pushed to understand “genuine needs” - the foundation of an effective solution. Mentors and speakers with deep knowledge on such needs are ready to assist during the whole process.

All undergraduate students are encouraged to participate!


The date for PEID Fall 2019 are in the works, scheduled for some time in November. Applications will open in early October; check back again for updates!
