2024 REU Summer Student - CLASSE and CBB

The REU program is open, by NSF regulation, only to US citizens and permanent residents. If accepted, you will be required to show proof of citizenship or permanent residency. This program is intended primarily for sophomore and junior students in science and engineering. In exceptional cases first year students could have enough familiarity with physics, engineering, or computer science to profit from their research experience. Students who have not yet enrolled as undergraduates and students who will have a Bachelors degree by the summer of 2024 are not eligible according to NSF regulations. If accepted, you will have to show proof of health insurance coverage for the period of the REU Program.

Living in Ithaca

Ithaca is a large town surrounded by rolling rural hills and home to some of the northeast’s most attractive gorges and waterfalls with amazing places to go swimming. The centerpiece of the landscape is Cayuga Lake — 40 miles of (mostly) clear, pristine water and a boon for sailing enthusiasts, with a number of parks along its shoreline.
