Curriculum Vitae

Research interests

Ecotoxicology studies on the impact of environmental pollutants on reproductive health are an emerging issue. Reproductive success is the key factor for the survival of the species and is strongly influenced by the surrounding environment in which the organism lives and reproduced. The marine environment is continuously subjected to anthropogenic pressures, whose main effects are the introduction of contaminants and climatic variations. Marine organisms characterized by external fertilization release gametes into seawater where fertilization and embryo development occur; consequently, any chemical-physical stressors, altering the quality and/or physiology of gametes and embryos, impact reproductive success with serious consequences for species fitness and survival and with possible repercussions on marine ecosystem biodiversity and functionality. My attention is focused on aspects of reproductive toxicology, in particular, on the study of the effects of chemical-physical stressors on gamete quality, fertilization and embryo development in different marine invertebrates. Using an integrated ecotoxicological approach, which includes standardized and innovative biological assays and analysis of gamete quality biomarkers, I study the biological responses induced by exposure to classical and emerging contaminants and physical stress; these allow to elucidate the mechanisms that mediate biological damage associated with pollution and provide tools for assessing marine environmental quality.
