I am a system scientist and aquatic biogeochemist focused on the study of ecosystem functioning in inland and marine waters and their responses to environmental drivers. I am interested in understanding the links between functional diversity and biogeochemical cycles in aquatic ecosystems, as well as the resilience of ecosystems to global change. My work has been focused on the interactive effect of multiple stressors (Tª, UVR, Nutrient inputs, CO2, Aerosol dust deposition) on planktonic populations and aquatic food web interactions following different approaches, molecular, physiological and stoichiometry. Our studies combine long-term field observations, in situ mesocosms experiments, laboratory experiments with microbial communities, and modelling. The ultimate goal of this research is to obtain a mechanistic understanding of nonlinear responses for the non-additive effects of natural and anthropic disturbances across organization levels. Current topics under investigation include: (i)· Role of temperature and resources in controlling metabolic balance of the ecosystem, (ii) Effect of environmental fluctuations on microbial community, (iii) Evaluation of the sequential action of global stressors, pay special attention to extreme climatic events in Mediterranean region
