Electromagnetics
Before his work on neural networks, Giles published papers on reflection and scattering of electromagnetic waves from magnetic materials for the particular cases of equal refractive indexes. His work is mentioned in the following articles:
Fresnel equations
The Fresnel equations (or Fresnel coefficients) describe the reflection and transmission of light (or electromagnetic radiation in general) when incident on an interface between different optical media. They were deduced by Augustin-Jean Fres ...

, he is a coauthor on the Kerker effect, which was an extension of his work on a planar boundary effect and his idea.
Neural networks
Giles' work on neural networks showed that fundamental computational structures such as regular grammars and finite state machines could be theoretically represented in recurrent neural networks. Another contribution was the Neural Network Pushdown Automata and the first analog differentiable stack. Some of these publications are cited as early work in "deep" learning.
CiteSeer and search engines
In 1998 and 1999 his work published in ''Science and Nature'' with Steve Lawrence estimated the size of the web and showed that search engines did not index that much of it. This work also showed that the web had significantly matured and had a diversity of material and resources.
