David Toms is Reader in Mathematical Physics in the School of Mathematics and Statistics at Newcastle University. Prior to joining Newcastle University, Dr Toms was a NATO Science Fellow at Imperial College London, and a postdoctoral fellow at the University of Wisconsin-Milwaukee. His research interests include the formalism of quantum field theory and its applications, and his most recent interests are centred around Kaluza-Klein theory, based on the idea that there are extra spatial dimensions beyond the three obvious ones.
