Nina Claire Snaith is a British mathematician at the University of Bristol working in random matrix theory and quantum chaos.

[1] In 1998, Snaith and her then adviser Jonathan Keating conjectured a value for the leading coefficient of the asymptotics of the moments of the Riemann zeta function.

Keating and Snaith's guessed value for the constant was based on random-matrix theory, following a trend that started with Montgomery's pair correlation conjecture.

Keating's and Snaith's work extended works[3] by Brian Conrey, Ghosh, and Gonek, also conjectural, based on number theoretic heuristics; Conrey, Farmer, Keating, Rubinstein, and Snaith later conjectured the lower terms in the asymptotics of the moments.

[4] Snaith's work appeared in her doctoral thesis Random Matrix Theory and zeta functions.
