Nick Burnham, one of the last Donaldson, Lufkin & Jenrette (DLJ) equity finance team members left after the Credit Suisse First Boston (CSFB) purchase last year, has joined the London office of Citadel Investment Group.

Citadel, a $4.5bn (€4.8bn) convertible bond and merger arbitrage hedge fund, is set to make one or two more hires in London as well as open a Tokyo office, said John Di Rocco, the Connecticut-based chief financial officer.
