Alex Fernandez-Martinez received his Ph.D. from the University Joseph-Fourier in Grenoble, France. His Ph.D. thesis was focused on the structure an reactivity of poorly crystalline minerals and their anion retention capability in different environments such as volcanic soils or acid mine drainage affected sites. He performed part of his Ph.D. at the Institut Laue-Langevin (Grenoble, France) where, prior to his Ph.D., he had used neutron scattering techniques to the study of amorphous and nanocrystalline materials. During his postdoctoral work at the Energy Frontiers Research Center for Nanoscale Control of Geologic CO2 (LBNL, Berkeley, USA), he performed studies on the thermodynamics of carbonate mineral nucleation, amorphous carbonate minerals and on diverse nucleation pathways relevant for CO2 seqauestration mechanisms. Alex is currently a staff scientist at the Institut des Sciences de la Terre (CNRS, Grenoble), and keeps and an active collaboration at the Energy Frontiers Research Center for Nanoscale Control of Geologic CO2 at the LBNL (Berkeley, USA).
