Valerie Trouet

Valerie Trouet is a Belgian-American dendrochronologist — a scientist who studies tree rings to reconstruct past climates and ecological conditions — and a professor at the Laboratory of Tree-Ring Research at the University of Arizona. Born in Belgium, she pursued her education and early career in Europe before moving to the United States, where she has become one of the leading figures in the field of paleoclimatology. Her research uses the annual growth rings of trees as a natural archive, unlocking records of temperature, drought, and ecological change that stretch back centuries and sometimes millennia.

Her popular science book, Tree Story: The History of the World Written in Rings (2020), translates the science of dendrochronology into an accessible and gripping narrative for general readers. The book traces the history of tree-ring science from its origins through its modern applications, showing how the rings of ancient trees have helped solve historical mysteries, predict drought cycles, reconstruct past climates, and illuminate the rise and fall of civilizations. Trouet writes with clarity and enthusiasm, making the technical methods of her field genuinely exciting while demonstrating their relevance to contemporary concerns about climate change and environmental resilience.

The book was widely praised by scientists and general readers alike for its ability to convey the wonder of a specialized scientific discipline without sacrificing depth or rigour. It demonstrated that the patient reading of nature — in this case, of the growth patterns laid down in wood year by year — can yield insights of the greatest importance for understanding the past and anticipating the future.

Trouet’s career exemplifies the best of science communication: a researcher of international standing who has found ways to bring her work beyond the academic literature and into the hands of curious general readers. Her book has helped raise public awareness of dendrochronology as both a scientific tool and a profound way of listening to what the natural world has recorded.
