Professional resume
Specialized in mass spectrometry analysis applied to the determination and structural characterization of organic pollutants and their transformation products.
Researcher (CONICET) and undergraduate professor (UNSAM).
PhD Chemistry and graduate degree in Chemistry, Universidad de Buenos Aires.
More than ten articles published in international peer reviewed journals.
Expertise
Development of methodologies based on mass spectrometry for the determination of organic pollutants and their transformation products. Chemical analysis of pollutants allows to study the presence of these compounds in the environment, to estimate their concentration levels, to identify their sources and to determine their degradation products. Identification of transformation products allows to understand their reactivity and stability, being useful for the development of bioremediation strategies, toxicologic and metabolic studies, as well as the analysis of environmental samples and the assessment of efficiencies of treatment processes.
Keywords
Mass spectrometry; Organic pollutants; Transformation products.
