    I am still passionately interested in lighting after having spent most of my working life involved in various aspects of the industry.

    I have now retired from TRILUX Lighting but will reman very much connected with the lighting industry.

    I am currently a Vice President and a Fellow of the Society of Light and Lighting where I enjoy stimulation from my peers, learning as much as I can from them, then using all the opportunities open to me to pass this on to others. I am excited by the future that this fast moving industry will bring.

    Sustainability is a topic that concerns me and so much of the work I am now involved with revolves around this subject.

    I am happy to spend this next phase of my career with the enthusiastic and dedicated people who form the lighting community.
