If you would like to find out more, please look at the papers onmy personal home page. Complex and nonlinear systems with interesting instabilities, dynamics, phase transitions and variable structure abound in engineering, and I have a broad interest in applying new theory so that these systems can be better understood and their performance improved. My industrial research background is the simulation of switching circuits, and my doctoral thesis describes fractal structures in a chaotic oscillator. In the past I have worked on applying bifurcations to understand and avoid voltage collapse blackouts and various other engineering applications of nonlinear dynamics. I am currently interested in understanding and quantifying the risk of blackouts using ideas of cascading failure and self-organized criticality from probability, physics and engineering.
