Postdoctoral Researcher - Water Resources & Environmental Geology

Fernando Gázquez Sánchez

I studied Environmental Sciences at the University of Almeria and I have a PhD in Environmental Sciences from the University of Almeria. I have been FPU fellow (2008-2012) at the University of Almeria and postdoctoral fellow at the universities of Valladolid (2013-2014), Cambridge (UK, 2014-2017), St. Andrews (UK, 2017-2018) and Hipatia fellow at the University of Almeria (2018-2020). Since 2020 I am a Ramón y Cajal contract holder of the Ministry of Science and Innovation. I teach in the degrees of Environmental Sciences, Chemistry and Agricultural Engineering, as well as in the masters of Sustainable Uses of Natural Resources and Ecosystem Services and Teaching.

RESEARCH

My research focuses on the study of minerals from caves and lakes to reconstruct the climate of the past. To do so, I use geochemical tools, such as stable isotopes of oxygen and hydrogen. I also participate in studies on caves as Martian analogues and I am part of the team of researchers studying the formation processes of the Giant Geode of Pulpí.
