All my writing has purpose. I like to base my work on sound science, social and environmental reality, human psychology and philosophy.

I am intrigued by the concept of infinity, by quantum theory, string theory, black holes and quasars.

As a biologist I studied genetics and have kept up with the developments in genetic engineering. I am intrigued with the idea of how this could impact on human development and that of all other living creatures and plants. We now have the power to change, improve or create both ourselves and the plants and animals we share this planet with. We can create different human beings, different species and a different world.

I studied psychology as part of my degree and found this incredibly useful in education. I also apply it to my writing. It is useful to build characters around psychological traits and personality types.

Living through the twentieth century has provided me with a great perspective on social change. I doubt any other century has seen such a degree of transformation. Science propelled a social revolution that changed the world. That is a useful element to draw into my writing. What changes are going to shape our progress? What will a future world look like?

As a biologist I have been greatly distressed by the impact mankind has been having on the environment. Extinction rates have soared as humans destroy habitat and pollute ecosystems. Our sheer numbers are swamping nature. Once the world was considered infinite and nature something to be exploited without thought. We now realize this is not the case. Even our primitive hunter/gatherer ancestors greatly impacted on the environment. Now we have the capacity to destroy it to a far greater extent. If our numbers and activities are not regulated we may well ruin the very life-support system that sustains us. It is a theme that occurs in most of my work.

What is the purpose of life? It is a question most of us ask at some point and it is one that has a basis in my writing. Whether it be spirituality or creativity, accruing material wealth or power, or seeking truth, wisdom, happiness or fulfilment, it is one of the factors that drives human beings. It is a theme worth developing. It brings people into conflict.

Whether setting the action in the future, in a different dimension or an alien world, these are themes that I tend to enjoy exploring.
