Works in decomposition processes and biogeochemical cycles of the elements in salt marsh sediments and its application in phytoremediation and bioremediation processes. Salt marsh vegetation ecophysiological biomarkers of metal contamination and photosynthetic mechanisms of salt marsh plants, are another point of study. Presently is investigating carbon dioxide dynamics in salt marsh ecosystems and the role of salt marsh plants and their different photosynthetic metabolisms in carbon retention processes. Carbon cycling between salt marsh vegetation, sediments and the water column in the context of climate change is another interest of the present investigation. Also studying the halophytes proteomic and ecophysiological response to multiple stresses (metal contaminants, global warming, excess carbon dioxide and sea level rising).
