Current Position

I am a researcher (Marie-Skłodowska-Curie Fellow, started on March 2021) at the Department of Natural Systems and Resources (Departamento de Sistemas y Recursos Naturales) of the School of Forest and Environmental Engineering (E.T.S.I. de Montes, Forestal y del Medio Natural) of Universidad Politécnica de Madrid (UPM). The main project I am currently developing is titled Predicting mixed FOrests REsponses to Climate change And drought STress with a plant hydraulics model (FORECAST).

My Research

Plant hydraulics, plant pathology, forest ecophysiology, and forest conservation

My research mainly focusses on plant pathology, plant hydraulics, forest ecophysiology, and forest conservation. I am interested in understanding how plant communities respond to different environmental stress factors such as drought, disease, and human disturbance. This knowledge is critical for predicting ecosystem responses to global climate change and for establishing adequate forest management practices and conservation and restoration policies. The research I perform includes several scales, ranging from organ level physiological processes to whole stand processes, and multiple tools including detailed physiological measurements and model development.

Research trajectory

I have always been interested in understanding how forest ecosystems function and most of my hobbies are outdoor activities. This led me to study a BSc in Forestry Engineering at Universidad Politécnica de Madrid (UPM). I first got involved in research as an undergraduate, investigating intraspecific diversity of Spanish pine species. The main objective of this project was to guide pine forest genetic resources management and conservation. After I graduated from my BSc in 2006, I joined a two-year MSc program in Environmental Sciences at UPM. During my MSc I worked for the Spanish Elm Breeding and Conservation Program, where I studied the Dutch elm disease (DED) pathosystem and the effects of DED on Spanish riparian forests. I also participated in breeding activities focused on obtaining elms (Ulmus spp.) resistant to DED.

I received my PhD from the Program in Advanced Forest Research at Universidad Politécnica de Madrid (UPM) in November 2013. My PhD supervisors were Dr. Luis Gil and Dr. Carmen Collada, and the title of my PhD thesis was “The ecology of the European white elm (Ulmus laevis Pallas) in the Iberian Peninsula”. I studied the genetic diversity, reproductive biology, seed dispersal capacity, and ecophysiology of the white elm in Spain. The results of my PhD thesis showed that white elm is a native species and endangered in the region. Based on these results I proposed conservation policies for the species.

My first postdoctoral position was at California State University Bakersfield (USA) working with Dr. Anna L. Jacobsen and Dr. R. Brandon Pratt. During this postdoc I studied the relationship between California chaparral plant hydraulic traits and drought-induced mortality. I also conducted several studies which evaluated techniques used for measuring plant hydraulic traits.

From 2016 to 2021 I was a Postdoctoral Research Fellow at the School of Biological Sciences of the University of Utah (Salt Lake City, USA), where I worked with Dr. John S. Sperry and Dr. William L.R. Anderegg developing, testing and applying a model that predicts plant responses to environmental variables from key plant hydraulic traits. In March 2021, I started my current position at Universidad Politécnica de Madrid.


Predicting mixed FOrests REsponses to Climate change And drought STress with a plant hydraulics model (FORECAST)

The frequency and intensity of droughts are expected to increase in many regions of the world due to global climate change. Droughts can lead to widespread tree mortality, leading to a loss of carbon stored in forests that will feedback to exacerbate climate change. Thus, modelling forest responses to drought is critical for predicting climate change socio-economic and ecological impacts and informing conservation strategies. However, current models are not capable of adequately representing forest responses to drought, especially for mixed forests due to their diversity in species and functional traits. The proposed research intends to solve this problem by developing a model for mixed forests based on known biophysical constraints, plant functional traits and optimization theory.

Predicting drought-induced tree mortality

Why do some trees die while others survive during a drought? What traits make a species more resistant to drought-induced mortality? Can we predict tree mortality? What traits maximize the fitness of a species within a given environment? How do plants acclimate to changing environmental conditions? Better understanding of plant traits coordination and acclimation is essential for shedding light on these questions. Thus, I am currently exploring how plant traits, such as rooting depth, xylem resistance to cavitation, and photosynthetic capacity, are coordinated for maximizing productivity and avoiding drought stress. The ultimate goal of this project is improving predictions of forests responses to drought.

Xylem structure and function

Trees need to supply a large amount of water to their leaves in order not to desiccate, because they lose hundreds of molecules of H2O for each molecule of CO2 they assimilate. Water is transported from the soil to the leaves through conduits in the xylem (wood) under negative pressure. During periods of low water availability xylem pressures become more negative and air-bubbles can be pulled into previously water filled conduits. These bubbles expand forming emboli that block water transport. This process is called cavitation. I am studying how different conduit characteristics and their 3-dimensional interconnection influence xylem resistance to cavitation.

Ecology and conservation of elms

Dutch elm disease (DED) has killed millions of elms (Ulmus sp.) across North America, Europe, and Asia, severely affecting the riparian ecosystems in which they live. The causal agent of DED is the fungus Ophiostoma novo-ulmi, and bark beetles are the propagation vector of the disease. I collaborate with GFH Forestal Research Group from Universidad Politécnica de Madrid (Spain) studying different aspects of DED pathosystem and the ecophysiology of elms to support the Spanish Elm Breeding and Conservation Program. The knowledge generated helps implement sound elm conservation policies and guides riparian restoration programs.

I lecture the Protected Areas Management course as part of the Environmental Engineering Degree ( Grado en Ingeniería del Medio Natural) of Universidad Politécnica de Madrid. This course is coordinated by Prof. Inés González Doncel. This is a 6 credits (ETCS) course that focusses on the legislation affecting Protected Areas and on how to elaborate management plans for Protected Areas ( course curriculum).

I am an instructor for the Forestry Production course as part of the Biotechnology Degree ( Grado en Biotecnología) of Universidad Politécnica de Madrid. This course of 3 credits (ETCS) is coordinated by Prof. Rosana López Rodríguez. The course focusses on how biotechnology can be used towards improving forestry production and aiding forest conservation ( course curriculum).
