Google Scholar Profile


My scientific career was initially focused on plant abiotic stresses with emphasis in Potassium (K) nutrition, and recently in plant–microbe interactions where I acquired experience in the plant-arbuscular mycorrhizal (AM) symbiosis and plant-nitrogen-fixing nodule bacteria focusing on Phosphorus (P) and Nitrogen (N) nutrition.

I achieved a PhD degree at the University of Granada and Zaidin Experimental Station (EEZ-CSIC) in 2011 with biotechnological approaches that use Na+ and K+ transporters to improve tolerance to salinity and K nutrition efficiency in tomato plants. I moved as a postdoctoral researcher to the Biological Research Center (CIB-CSIC) to enhance my knowledge in plant abiotic stress (low temperature and drought) in tomato and Arabidopsis. Later, I was involved in several projects related on the regulation of AM symbiosis by plant hormones at EEZ-CSIC. Currently, I am working at Noble Research Institute with Michael Udvardi in several symbiotic nitrogen fixation (SNF) projects.

Research Areas:

  • Legume-Rhizobium symbiosis
  • Interaction of abiotic stress and SNF
  • Plant nutrition

Current N-related Projects:

  • Genome-wide association study to identify potentially-interesting genes that contribute to SNF effectiveness in Medicago truncatula.
  • Understanding the relationship between plant P homeostasis and N during SNF.
  • Exploring the interactions between ascorbate and SNF in Medicago truncatula.
