## Abstract

In this thesis, the author proves theorems on the distribution of primes by extending recent results in sieve theory and proving new results on the distribution of zeros of Rankin-Selberg L-functions. The author proves for any number field K which is a Galois extension of the rational numbers, there exist bounded gaps between primes with a given "splitting condition" in K, and the primes in question may be restricted to short intervals. Furthermore, we can count these gaps with the correct order of magnitude. The author also proves log-free zero density estimates for Rankin-Selberg L-functions with effective dependence on the key parameters. From this, the author proves an approximate short interval prime number theorem for Rankin-Selberg L-functions, an approximate short interval version of the Sato-Tate conjecture, and a bound on the least norm of a prime ideal counted by the Sato-Tate conjecture, all of which exhibit effective dependence on the key parameters.
