Sc., 1976) and theoretical physics at the Weizmann Institute, Rehovot (Ph.D., 1985), where his graduate advisor was Yitzhak Frishman.
His early work focused on non-perturbative quantum field theory in two space-time dimensions.
He made important contributions to the study of Rational Conformal Field Theory with extended chiral algebras.
He also pioneered the use of methods of conformal field theory to study compactifications of superstring and heterotic string on Calabi–Yau manifolds.
[2] Gepner's later work centered on Rational Conformal Field Theory and its relation with 2D integrable models.
