Research Activities My research activity is focused on ecological study of wetland and transitional waters. These environments are affected by increasing load of nutrients and organic matter that is a direct consequence of human activities (e.g. sewage discharge, fish farming, agriculture and industry). Therefore high level of eutrophication and an increasing of dystrophic events are leading to a massive loss of the biological resources. The main topics of my research activity are: a) Bioindicators - Variability of macrozoobenthic assemblages The bioindicators are relevant tools for assessing the effect of anthropogenic activities on the marine environments. The macrozoobenthic assemblage study allows identifying the level of environmental stress and degradation due to organic-pollution. To carry out these studies, a set of biological tools have to be measured since they have high ecological relevance which includes: distribution changes, altered abundance and reduced diversity. b) Stable Isotope (SI) – Study of biodiversity The stable isotope technique (SI) can be useful to understand the relations among trophic levels in aquatic ecosystems. In environments subject to rapid dystrophic events, qualitative and quantitative changes in the trophic composition can be expected. SI technique can be effective in such instances in investigating temporal changes in food web structure and the recovery of the affected ecosystem. c) Biogeochemical modelling LOICZ (Land-Ocean Interactions in the Coastal Zone) In aquatic ecosystems, the development of water eutrophication is leaded by the interactions between biological and geochemical processes, through the trophic level and in relation to the phosphorus cycle. The trophic status is affected not only by increased primary production and organic matter enrichment, but also by morphology, hydrodynamics and multiples stressors. The study of carbon and dissolved nutrients cycles can not be carried out accurately, without the biogeochemical modelling. In fact these models are able to handle the complex link between humane activities and ecosystem functioning, which are impossible to be captured with more traditional statistical tools.

Comments I have always been interested in the ecological study of wetland and transitional waters, and in the impact of the human activities on these environments. These are characterized by high levels of productivity, and play a life-support role for several species like invertebrates, fish, birds and mammals; most of these species have an important economic role either directly in fisheries or in ecosystem services such as coastal protection. I believe that from a human prospective, the study and conservation of these systems play a key role in the investigation of the different strategies that must be made for a sustainable development of these renewable resources. In my previous experiences, I had the opportunity to learn the most relevant skills and competences to carry out a research activity, including: • field survey, sampling activities, data management and data analysis; • taxonomy skills particularly, classification of macrozoobenthic species; • gained familiarity with different lab protocols; • a demonstrated ability to work at sea on board research vessels and boat-handling.
