Laia Andreu-Hayles is a Research Associate Professor at the Tree-Ring Lab of Lamont-Doherty Earth Observatory of Columbia University and a lecturer at the School of Professional Studies of Columbia University. She holds a B.S. in Biology from the University of Barcelona and defended her Ph.D, which received a European Doctorate award mention, in October 2017 in Spain. Her research is focused on the study of past, current and future environmental changes, and incorporates dendrochronology and isotopic geochemistry. Her career has been focused on the assessment of vegetation responses under global climate change and on reconstructions of past climate. She seeks to understand the interactions between forests and the environment to provide a long-term context for the study of current anthropogenic change, its impacts on the terrestrial ecosystem, and the Earth’s climatic system. Her investigations are ongoing at sites located in the Mediterranean, boreal and tropical regions, which are “hot spots,” where some of the most dramatic environmental changes are already occurring.
