School of Computer and Mathematical Sciences
Computing and mathematics are important for changing the world as well as dealing with a changing world. Many of the major problems currently facing the planet, such as energy conservation, climate control, finding new drugs for disease, preventing identity theft and the criminal activity on the Internet, all rely on new ways to use computing and of finding new mathematical solutions to global problems.
The School of Computer and Mathematical Sciences has strong research interests in Applied Mathematics and Computer Science, especially Astronomy and Cosmology, Computational and Mathematical Finance, Distributed and Adhoc Networks, Mobile Systems, Computer Graphics and Game Programming.
