Overview

I am research fellow at CSM, I am currently working on a project to develop new ways to valorise sulfidic tailings. My primary research will focus on developing and testing innovative bio-leaching processes using acidophilic microorganisms under the project NEMO. I have worked previously at Bangor University in the Bangor Acidophile Research Team (BART). Within my research I have studied how to recover valuable metals from different ores and concentrates, and mine wastes, bioremediation of acid mine drainage, I have also isolated and characterized new acidophilic microorganisms. I also study the microbiology of acidic mine pit lakes in the Iberian Pyrite Belt and how these affect and are affected by the hydrogeochemistry of the lake waters. I would like to continue my research working with microorganisms and their use on biotechnological applications such as biomining, and bioremediation. I am also interested in studying the stability and securing mines and mine wastes and the exploration of new strategies to recover valuable metals from wastes.

  • PhD Microbiology of acidic mine pit lakes of the Iberian Pyrite Belt (University of the Basque Country and Geological Survey of Spain, Spain)
  • MSc Oceanography (University of Cadiz, Spain)
  • BSc in Conservation Biology (University of Alcala de Henares, Spain)
