QUBSU meaning in Academic & Science ?

Queen's University Belfast Students' Union (QUBSU) is the official representative body for students at Queen's University Belfast. Membership of the union is automatic and currently totals 24,560, making it one of the largest unions on the island of Ireland and in the United Kingdom. The Students' Union derives its existence and authority from the University's Statutes, and so is not entirely independent of it. Therefore, it must have amendments to its constitution approved by the University Senate. It aims to represent students' interests both with the university and the wider community, to create a sense of student spirit and provide services that aid its student members during their time at Queen's. The Students' Union can trace its origins to the nineteenth century, and has been based on University Road, directly opposite the University's main 'Lanyon Building', since it opened in 1967.
