My profile
Biography
I was awarded a Ph.D degree on Automatic Control with PhD thesis on developing new methodology to design control laws for hybrid systems. I was a research assistant at the University of Glasgow. I was then appointed Lecturer in Electronics Engineering at the School of Systems Engineering at the University of Reading in October 2001, Senior Lecturer in Mathematical Engineering in 2009 and Professor in Mathematics and Engineering in 2014. I have now recently been appointed at the Manchester Metropolitan University as Professor in control Engineering.

Research outputs
My research program has concentrated on furthering the field of control theory and modelling. My early work was focused on hybrid dynamical systems. This work culminated in the development of the Hamiltonian systems on Lie Group, and that has become widely recognised nationally and internationally through seminar invitation in Universities worldwide. Over the past fifteen years I have applied my control expertise to several applications and in particular rehabilitation engineering and energy transmission, storage for electrical systems, and power systems. In rehabilitation engineering a major contribution was techniques for controlling the trunk standing up using electrical stimulation. Furthermore my research in energy storage has given promising result in the use of multiple agent systems and intelligent control to minimise energy consumption when using multiple storage combined with harvesting technology. Novel research in creating a model of wireless power transfer has enormous potential in the automotive industry and already early results through publications has shown promising results. Finally my research is also in autonomous flying vehicle and in particular in the area of motion planning and visualisation.
