I am an evolutionary ecologist focused on understanding how forest tree species respond to climate, particularly drought, the functional mechanisms involved in such a response and the potential of populations to face climate change. I am especially interested in elucidating the roles of phenotypic plasticity, genetic variation and adaptive evolution of functional traits for forest tree populations to respond to a drier climate. I address these questions by using techniques and analyses from different fields such as quantitative genetics, ecophysiology and genomics which provide a multidisciplinary perspective to my research.
I obtained my PhD in Advanced Forestry Research from the Technical University of Madrid (UPM, 2010). As a postdoc, I have developed my work in the Spanish Institute for Agricultural and Food Research and Technology (now ICIFOR-INIA, CSIC), Australian National University, University of Minnesota, Doñana Biological Station (EBD-CSIC) and National Research Institute for Agriculture, Food and the Environment (INRAE-Pierroton).
