I am an Associate Professor at the Department of Ecology in the University of Granada (UGR) since 2003. I got my PhD in this university in 1995 working on the influence of nutrient recycling on microbial food web in alpine lakes. From 1995-1998, I was a postdoc at the Institute of Ecosystem Studies (IES, now Cary IES) working on bio- and photo-reactivity of dissolved organic matter in temperate lakes. Since my return to the UGR, I has been working on the influence of Saharan dust on aquatic ecosystems and its role as vector of microbial dispersal. In addition, I enjoyed several oceanographic projects (Southern Ocean and Malaspina 2010 Circumnavigation) with goals related with the importance of dissolved organic matter and exopolymer particles in global carbon cycle. Currently, I working on C and N biogeochemistry, green house gases fluxes and microbial ecology in saline wetlands, and reservoirs.
