I am currently working as a postdoctoral researcher at the Global Ecology Unit (CREAF-CSIC-UAB, Catalonia). My research combines several disciplines in Ecology: plant biology, fungal biology, community structure, functional ecology, ecosystem dynamics, plant-soil interactions and diversity patterns. I have been doing research on contrasting ecosystems across the world: in alpine (Pyrenees, Himalaya), subarctic (Scandes), arctic (Greenland), tropical (French Guiana), and in mediterranean regions (Catalonia). I have conducted observational and experimental studies in most of these regions to analyse the effects of environmental variability on ecosystem functioning.

My research has focused on the measure of VOC emissions from plants, especially focusing on floral scent. I am especially interested in understanding the factors that exert evolutionary pressures determining floral emissions at the species and population level, and also the environmental factors that affect these emissions at the organism and tissue level through their effects on plant physiology and VOC physicochemistry. I am also interested in exploring the effects of such changes in floral scents on the ecological interactions that these emissions mediate with diverse floral visitors (pollinators, larcenists, florivores).

I am an ecologist broadly interested in the effects of multiple stressors –natural or human related− on the functioning of ecosystems. I earned my degree in Environmental Sciences, and then moved to the Marine Ecology for my PhD. Much of my research interests lie at the intersection of environmental processes and human activities, and I am particularly enthusiastic about those projects that try to bridge science and resource management. I have worked in research institutions of Spain, the UK, and France, and in projects concerning terrestrial, marine and freshwater issues. My work so far has been focused on two major axes: (1) The functioning of coastal marine ecosystems, and specifically the response of plankton to changes in nutrients and turbulence; (2) The land-ocean interface, in particular the links existing between water resources, the agro−food system, and the flows of N and P to the environment. I am currently focused on characterising the N and P biogeochemical cycles in Mediterranean river basins.

I am a post doctoral researcher with a Juan de la Cierva funding. I did my undergraduate in Environmental Science at the University of Nottingham. Then I did my master in Biogeochemical cycles and Atmospheric Sciences in Lund University, Sweden. After I did my PhD in climate and the environment at the Brazilian National Institute of Amazonian Research (INPA) in co-supervision with the Max Planck Institute of Chemistry. Afterwards I continued as a post doctorate researcher for MPIC in the Amazon. My research was based on the interactions of volatile organic compounds (VOCs) within and above a central Amazonian tropical rainforest. My latest position as a Post doctoranl researcher was at Freiburg University (Germany), working in a ERC grant trying to find out how much carbon is emitted by plants through secondary plant metabolism from tropical plants.

I am interested in the interaction between forest ecosystems and the atmospheric chemistry. Forest can react very quickly to changes in environmental factors, and up to date, not all processes have been described or elucidated. As global temperatures increase and climate change exacerbates it is important to understand how forested areas will react to such changes, as the impact in atmosphere can be very large, from direct global warming via aerosol and carbon dioxide production, increase the atmospheric lifetime of pollutants, or even alter rain distribution locally. We need to provide better information for modellers, so they can constrain the processes governing the forest atmosphere interactions so better guidelines on mitigation and adaptation strategies can be suggested to policy-makers.

The relationship between soil fauna and humus accumulation along the altitudinal gradient were investigated. Exploring the functional groups of soil animals at different altitudes, and soil community and diversity at different soil layers. Moreover, the contribution of soil animals to litter humification on the elevation gradient and the accumulation of humus in different soil layers on the elevation gradient were studied. Furthermore, the effects of refractory substances, easily decomposable substances and elemental components on the accumulation of litter humus sustained by soil fauna were explored.

The aim of my PhD thesis is to discuss the role of phosphatases in agroecosystems using scientific articles published around the world. Phosphatases are enzymes catalyzing the hydrolysis of both esters and anhydrides of phosphoric acid and its measure is important to know the mineralization of P in soil and the response of these enzyme activities to changes in environmental factors, agricultural management and pollution. Fundamentally most of the experiments use the rapid enzyme assay based on p-nitrophenyl phosphate (pNPP) by Tabatai and Bremmer (1969) although this method has suffered upgrades. And in parallel other methods started to use artificial substrates which are well documented. All the present enzyme assays in each method measure potential and not real enzyme activities because every assay conditions are different from those occurring in situ. In my project I want to link the assays all over the world from the beginning to the present. My objective is to try to find relationships and patterns between the phosphatase’s activity in different conditions based on, for example, fluctuations of temperature and moisture of the soil, pH and substrate concentration, shaking, soil slurry...etc.

I am currently a predoctoral student at the Ph.D. in Terrestrial Ecology at the UAB and CREAF. My research aims to improve the understanding of the functioning and dynamics of tropical forests through the application of the functional approach, and focuses on the study of; 1) the intraspecific variability of the functional traits of plants and their relationship with the ecosystem service of carbon sequestration; 2) the morphological and functional responses of seedlings to disturbances (drought, fire, and herbivory) and their potential use as predictors of changes in the growth of species during seedling establishment. Recently, I have studied the restoration processes, the production, and decomposition of litter, and the dynamics of nutrients in tropical forests.

The carbon and nitrogen dynamics across ecosystem components can provide a new strategy for elucidating biogeochemical cycles, and have increasingly been used to assess how aboveground and belowground systems respond to global climate change. Generally, terrestrial C and N cycles are indicated by changes in C and N dynamics in plants, soil, and microorganisms through their impacts on ecosystem production and decomposition processes. There remains considerable disagreement concerning the potential effects of global changes in C and N dynamics. Interactive effects among multiple concurrent global changes can have complex and prominent effects. To gain a better understanding of how global changes influences C and N dynamics in terrestrial ecosystems, it is useful to synthesize the disparate results of individual studies. The work enables a comprehensive evaluation of the effects of global changes and can guide management decisions.

The area I am now focus on the relationship between biogeochemical cycle of iron and C/N cycles. During my two-year study, I have accumulated a lot of experimental experience and now I am studying about iron-mediated soil C mineralization and greenhouse gas emissions on a global scale.

Prediction of Foliar Concentration to understand the mechanism of complex ecosystem. Indeed, to draw generalizable and robust conclusions from observations, it is essential to incorporate the ecological spatial-temporal data and climate information into explainable artificial intelligence modeling frameworks. In this study, aim is to predict the European foliar concentration maps of carbon fertilization effect on vegetation photosynthesis, based on ecological spatial-temporal datasets. Therefore, we use the framework of explainable and interpretable machine learning models to discover the complex interactions within the Carbon Fertilization Effect process.
