William D. Banks is a Professor in the Department of Mathematics at the University of Missouri. His area of specialization is NUMBER THEORY, which is concerned with properties of whole numbers, especially primes. With over 100 research articles in the literature, Banks has produced an extensive and diverse collection of results in both algebraic and analytic number theory, and in applied areas such as representation theory and cryptography. Banks collaborates with top researchers in the field, and his work has been supported by the National Science Foundation.

At present, Banks' work revolves around the Riemann zeta function, Dirichlet L-functions, sieve theory, and estimates of exponential sums.

As an instructor, Banks constantly strives to bring out the best in his students. He cares deeply about their future success.  In 2003, Banks received the Provost Outstanding Junior Faculty Teaching Award.


Banks also owns and operates BINKBALLS -- a Missouri company that offers for sale his works of art, raising money for various charitable causes. Founded in 2018.
