Eric Oelkers is currently a Research Director at the Centre national de la recherche scientifique in Toulouse France, Professor of Aqueous Geochemistry at the University of London, and Adjunct Professor at the University of Iceland. Eric and his research group of approximately 10 PhD and post-doctoral fellows perform detailed laboratory experiments to understand regional and global scale natural processes. Eric graduated with his bachelors degrees in chemistry and in Geology at the Massachuetts Institute of Technology and completed his Ph-D in Aqueous Geochemistry at the University of California, Berkeley. Over the past decade, Eric, together with his friends and collegues have made significant contribution to carbon capture and storage, quantifying the global cycles of the elements, sustainable management of energy and mineral resources, and improving the quality of our drinking water.

Jacques Schott received a Docteur es Sciences Physique degree from Toulouse University (1973). He defended his thesis, as a Fellow of the French Commissariat à l’Energie Atomique (CEA), on the chemical and isotopic fractionations induced in naturals systems by the coupling between diffusion, thermal gradients and natural convection (Soret and thermogravitationnal diffusions). After an Assistant Professorship at Toulouse University and a Research Associate position at Yale University (1979-1982), he has been since working within the Centre National de la Recherche Scientifique (CNRS) on the experimental and theoretical modeling of reactive transport in natural system linked to the fluid phase. For this purpose he has created a new experimental laboratory aimed at generating the values of the kinetic, thermodynamic and structural (Raman spectroscopy, RMN, EXAFS…) parameters on minerals, aqueous species and mineral-solution interfaces. This information is used for the modelling, at different spatial and temporal scales, of reactive transfers within the Earth’s crust and at its surface (diagenesis in sedimentary basins, hydrothermal processes, continental weathering, CO2 sequestering into the subsurface). Recent fields of interest are i) the quantification of the kinetics of crystal growth for carbonate and silicate minerals and ii) the kinetics and equilibrium fractionation of metals stable isotopes (B, Mg, Si, Ge, Ca, Zn…) during solid-solution interactions (dissolution, sorption, crystallization) as a function of metal aqueous speciation and reaction affinity.

Maria Cristina Castillo Alvarez completed her BSc in Environmental Science at the University of Texas at El Paso. She graduated in Applied Environmental Geoscience at the University of Tübingen, Germany, where she used stable isotopes of water to create a model of the transit time distribution of water flowing in the hyporheic zone of the Steinlach river. Maria Cristina originates from Mexico. She will become Early Stage Researcher at Géosciences environnement Toulouse.

Franziska Stamm completed her BSc at the University of Bonn investigating the experimental alteration of bone in acidic solutions in order to develop a better understanding of the process of fossilization. She continued her MSc studies at the University of Bonn in the field of bone geochemistry. For her thesis she studied the fluoridation of teeth dentin via real-time, in situ Raman analysis. In February 2015, she will take a position as Early Stage Researcher at Géosciences environnement Toulouse.
