During my predoctoral stage, my research has sought to understand the parameters controlling the viability and kinetics of fluid-driven mineral replacement reactions. This line of research has involved experimental work related to the alteration of Ca-carbonates and Ca-sulphates under experimental conditions mimicking diagenesis. With this aim, I have used techniques which have allowed me to characterise the chemical, textural and crystallographic features of the primary and secondary mineral phases before, during and after the replacement. These techniques include X-ray diffraction, electron microscopy, atomic force microscopy, mass spectroscopy, thermogravimetry, etc.

The development of my research has been possible thanks to my participation in two projects (CGL2016-77138-C2-1-P; PID2021-125467NB-I00), the obtaining of a predoctoral FPU fellowship (FPU17/01689) and the completion of several predoctoral stays at the Ludwig-Maximilians Universität (LMU) of Munich. The work of the pre-doctoral stage has resulted in the publication of several manuscripts and the participation in more than 20 national and international conferences. During my predoctoral stage, I also had the opportunity to teach subjects from the Bachelor in Geology (Complutense University of Madrid) like Mineralogy of Silicates, Mineralogy of non-Silicates, Crystallography and Mineral Characterisation Techniques.

Since 1 January 2023 I am working as a postdoctoral fellow at the GeoForschungsZentrum (GFZ) in Potsdam; in the Interface Geochemistry group led by Prof. Dr. Liane G. Benning (Section 3.5). In this group I am part of the European ERC Synergy Grant (856416) project "Deep Purple" (50%). This project studies what is causing the rapid darkening and decay of the Greenland Ice Sheet. Within this project, I am responsible for the mineralogical characterisation of polar samples, studying the role of mineral phases in (i) albedo variation and (ii) the growth of microorganisms in the ice due to the release of nutrients such as phosphorus or iron. I am also part of the "Interface Geochemistry" working group, where I continue my line of research regarding the genesis, growth and replacement of calcium carbonates and sulphates.
