My research career

In 2009, I graduated as a Forestry Engineer at the University of Lleida. Subsequently, in 2012, I completed a master's degree in GIT: GIS and Remote Sensing at the University of Zaragoza. In 2016, I obtained my PhD degree at the University of Zaragoza with the Extraordinary Doctorate Award. I developed my PhD thesis at the Pyrenean Institute of Ecology (CSIC) entitled "Role of biotic factors and their interactions with droughts in forest decline events", and under the direction of JJ Camarero (IPE-CSIC) and JC Linares (UPO).

In 2018, I joined UVa as a Juan de la Cierva-Training researcher in the Cambium research group ( at the Duques de Soria campus, under the supervision of JM Olano. In 2021, I started a contract as a Juan de la Cierva-Incorporation researcher.

Throughout my career, I have carried out several research periods in centers and universities abroad, such as: the Swiss Federal Research Institute-WSL (Switzerland), the IANIGLA-CONICET (Argentina) and the University of Tuscia (Italy). I have also participated in several national and European projects. I have recently obtained a project as PI in the 2020 call for R+D+i projects of the Spanish Ministry of Science and Innovation, entitled: "Winter is not coming: Understanding the pine processionary moth range of expansion in a context of global warming", and with the assignment of a predoctoral FPI contract.

My research

I study the impact of global change on forest growth and functioning. My research activity is mainly focused on 4 main axes: (i) understanding the response of deciduous forests to increased spring frost damage; (ii) determining the causes and consequences of forest decay phenomena in Mediterranean ecosystems; (iii) studying the influence of climate and historical land use changes on long-term recruitment dynamics; and (iv) understanding the causes of the expansion of some defoliating insect species such as the pine processionary. As main tools in my research I used dendrochronology (the study of tree growth rings), and remote sensing (remote sensing).

My vision is to understand how climatic and environmental changes determine the growth and dynamics of forests around the world, but with special emphasis on Mediterranean forests. My research deepens the understanding of the interactions between climate change, biotic agents and forest management. The ultimate goal is to answer ecological questions that allow establishing effective management measures in a context of global change.
