I studied at the Faculty of Natural Sciences and Museum of the National University of La Plata, where I hold a Doctorate in Natural Sciences and I currently work as Professor in the Chair of Populations Ecology. I am also a researcher at the National Council of Scientific and Technical Research, Argentina. I specialize in continental (freshwater and terrestrial) mollusks, which analyze microbiological (genetic and phylogenetic) and macroecological scales in landscapes and large hydrological systems, vulnerable to two major forces of change: anthropic and climate change. Organized, updated and geo-referenced mollusc databases, aimed at identification and control of species of a) biomedical importance: intermediary hosts (IH) of human parasites, domestic animals and cattle. b) pests of crops, HI of parasitic, exotic and invasive and c) conservation of native endemic species (biodiversity) and analyze their regional status (degree of endemicity) in biomes of South America.
