Roger Heath-Brown has made prolific contributions to analytic number theory; in particular, for his work on the Riemann zeta function and its higher moments, for his elucidation in collaboration with Samuel Patterson of the classical Kummer problem concerning the distribution of the arguments of cubic Gaussian sums, and for his work on the representation of zero by non-singular cubic forms in ten variables. He was awarded the Junior Berwick Prize of the London Mathematical Society in 1981.
