Diane is a Professor of Environmental Biotechnology. She is a Fellow of the Royal Society of Biology, the Institution of Environmental Sciences and a Titular Member of the International Union of Pure and Applied Chemistry.
As a Professor of Environmental Biotechnology with over 20 years’ experience in the field, in particular researching the role of microorganisms in protecting the environment, she is keen to make a meaningful contribution to raise awareness of microorganisms and the environment.
"Climate change and explosion in population growth are two of the most pressing issues facing the 21st century. There is an urgent need to ensure sustainable practices are used to meet population demands, such as food and energy security, without compromising the health of the environment. I believe microorganisms can provide sustainable solutions to safeguard and improve the environment. I wish to apply my expertise to champion the application of environmental biotechnology, to inform and bring together different stakeholders for the betterment of humanity."
