Trinity College Dublin (TCD) is the only college constituting the University of Dublin and thus both names are commonly used. It is the oldest University in Ireland, founded by Elizabeth I in 1592. Today there are about 17,000 registered students across all disciplines, almost 5,000 of them postgraduates. Although TCD was the home institution of Ernest Walton (Nobel prize 1951 together with Cockroft for their pioneer work on the transmutation of atomic nuclei by artificially accelerated atomic particles), there is currently no experimental particle physics group at TCD. However, the School of Mathematics has a group of theoretical physicists working on string theory and lattice QCD, including aspects of flavour physics and CP violation. Staff members of this group teach all the theoretical physics classes of the 4-year undergraduate degree course "Theoretical Physics", which is shared between the TCD Schools of physics and mathematics.
