What Is URSI??

Vassar's Undergraduate Research Summer Institute (URSI) is an intensive 10-week summer program in which Vassar students explore original hands-on scientific research under faculty direction. URSI participants are engaged in the entire research process: they learn to formulate hypotheses, review scientific literature, develop experimental protocols, handle major instrumentation, gather data, analyze results, and present their findings.
