Brief synopsis of current research:
Dr Edwards' research involves the use of naturally occurring isotopes as tracers in water and climate studies and in closely related aspects of environmental isotope geochemistry. His efforts and those of his research group aim to document and interpret variations in the relative abundance of the rare stable isotopes of oxygen and hydrogen in precipitation, surface and ground waters, as well as in materials like tree rings and lake sediments, as indicators of past environmental history and ongoing hydrologic and climatic change.

Comments:
My career path has been strongly influenced by my fascination with water, from splashing in puddles as a child to canoeing as a teenager. The field work that I do now allows me to indulge in water-play in places that I could never otherwise afford to visit, while generating new knowledge about the inter-relationships between water and climate and other aspects of the natural environment.
