During 1971–1973, he was member of the theory group at CERN.[2][5]
Starting in 1986, he had been professor of theoretical physics at Chalmers Institute of Technology in Gothenburg.[6] Brink was one of the pioneers of superstring theory, since the 1970s (at CERN and Caltech). He coordinated the EU network Superstring Theory 1991–1995 and 2000–2008.[7]
