I graduated in Environmental Sciences in Murcia (Spain) in 2008. Due to my particular interest in soil erosion and quality, I did an additional Master study specializing in Soil Management.

Currently, I am a PhD student in the group of Microbial Ecology, under the supervision of Prof. Heribert Insam, where I continue working with soils and the importance of using alternative nutrient sources in the frame of a global circular nutrient economy.

Integrating both classical and modern techniques, my work focusses on the application of wood ash and N-containing organic residues from bioenergy process as nutrient source and lime replacement in traditional fields such as composting, grassland amendment and forestry.
