Discovery Day is an annual poster show organized each May as the culminating event for seniors in the ENV Certificate program, as well as students who received research support from HMEI. In 2018, Discovery Day was expanded to include students concentrating in ecology and evolutionary biology.

Discovery Day provides Princeton University seniors and graduate students with an opportunity to display and discuss their research methodologies and results, to exchange perspectives, and to propose solutions to the world’s most pressing environmental challenges. Event attendees, including fellow students, faculty and university administrators, are treated to an extensive display of environmental research taking place at Princeton. For more information or questions regarding the event, please contact HMEI’s Undergraduate/Graduate Program Manager Amber Lee.

In 2019, 115 undergraduate and graduate students representing 19 academic departments exhibited posters on focal themes including: climate and environmental; science; biodiversity and conservation; land use; oceans; urban sustainability; energy technology; culture and the environment; water; and health. Coverage of past years’ events are below.

In 2020 and 2021, printed archives of undergraduate research were produced in lieu of Discovery Day events, which were not held due to the University being closed in response to COVID-19. Online versions of both booklets are below.
