GSU

GSU was a pre-War university located somewhere in the United States of America.

Background
T. Sullivan, a soda jerk in Vault 76, graduated from the university with a Doctorate in Engineering.

Appearances
GSU is mentioned only in Fallout 76.

Behind the scenes
It is not clear which university this is, as GSU can refer to several colleges in the United States, including Georgia State University, Grambling State University and Governors State University. In the real world, none of these universities offer a doctorate program in engineering, though this may be a case of divergence.
