My scientific interest is the water-rock interaction in the ecosystems and the human impact characterisation and remediation. I am particularly interested in the interface between Geochemistry and Hydrology. The incorporation of the water flux to the water-rock interaction is essential to understand geochemical processes. The coupling of chemical reactions to fluid flow is also indispensable to predict and remediate the pollutants behaviour. I have worked mainly in projects on acid mine drainage geochemistry, evaporites and on the development of reactive transport modelling and its application to the analysis of geochemical process.

I am graduated in Geology and doctor in Geological Sciences by the University of Barcelona in 1975 and 1981, respectively. I was pre-doctorate fellow of the British Council at Durham University (UK) during 1978-79, and postdoctoral researcher at the Universities of Yale and California-San Diego in 1990 and 1992, respectively. I was Associate Professor of Mineralogy and Mineral Deposits at the University of Barcelona from 1983 t o1990. I am presently Professor of Geochemistry at the Spanish Research Council (CSIC), and served at the Institute of Earth Sciences Jaume Almera (ICTJA) and recently at the new Institute of Environmental Assessment and Water Research (IDAEA). I was Director of ICTJA-CSIC from 2001 to 2005. I am co-author of more than one hundred twenty papers published in indexed journals, I directed or participated in more than thirty research projects, a dozen of them of international setting. I have supervised about twenty doctoral theses. I was Associated Editor of the European Journal of Mineralogy and of Journal of Hydrology. I served as President of the Spanish Mineralogical Society from 2009 to 2012.
