Mathematical career
Hjorth earned his Ph.D. in 1993, under the direction of W. Hugh Woodin, with a dissertation entitled On the influence of second uniform indiscernible. He held faculty positions at the University of California, Los Angeles and the University of Melbourne. Among his most important contributions to set theory was the so-called theory of turbulence, used in the theory of Borel equivalence relations.
Chess career
Hjorth won the Doeberl Cup in Canberra in 1982, 1985 and 1987 and played for Australia in the Chess Olympiads of 1982, 1984 and 1986.
His best single performance was at Brighton (BCF Championship) 1984, where he scored four of seven possible points (57%) against 2551-rated opposition, for a performance rating of 2570.
