Teaching

Analogue Electronic Systems (Undergraduate)

This is a Level 4 module introducing you to electronic devices, components, circuits and simple systems. There is particular emphasis on the basic theorems and techniques of electric circuit theory in relation to simple a.c. and d.c. circuits in order to provide a sound theoretical background to both analogue and digital modules in subsequent semesters.

Security and Authentication (Postgraduate/Undergraduate)

This module is concerned with the principles and practice used for secure communications in the Internet and aims to give students an introduction to the principles and practice of cryptography and authentication used for network security.

Research

Research Interests:

Characterisation and topological Modelling of Large Networks.
Catastrophic failures of Networks
