Research Interests :
My main research is in number theory, that is, the
study
of the properties of the whole numbers, especially by the use of
analytic
techniques. Particular subjects of interest are Waring's problem, the
Goldbach
problem, the Hardy-Littlewood method, the use of "smooth numbers", i.e.
numbers
without large prime factors, the distribution of prime numbers,
exponential
sums over integer sequences such as the sequence of primes, properties
of
the Riemann zeta-function and Dirichlet L-functions.
