PhD in Chemical Sciences | Specialist in Raman/FTIR Spectroscopy & Organic Chemistry

Profile Summary

I hold a Ph.D. in Chemical Sciences with over 10 years of experience specializing in physical and organic chemistry. Currently, I work as a researcher at National Scientific and Technical Research Council (CONICET), where my primary focus is the structural characterization and qualitative analysis of polymer materials utilizing confocal Raman microscopy and FTIR spectroscopy. Throughout my career, I have actively participated in high-level scientific research, providing essential analytical support by solving complex organic and physical chemistry problems and analyzing datasets. My doctoral research at CONICET focused deeply on the physicochemical interactions between peptides and lipid membranes. I have also been involved in the design and interpretation of complex experiments regarding photodynamic activity and nanoparticle stabilization, contributing to several peer-reviewed publications in prestigious journals such as Thermochimica Acta, Bioconjugate Chemistry, and Spectrochimica Acta. Alongside my research participation, I possess strong teaching experience at the National University of Mar del Plata and the National University of Tucumán, Argentina. I instruct undergraduate students in organic chemistry, specializing in breaking down reaction mechanisms and molecular structures into clear, structured explanations. I am highly motivated to leverage my deep expertise in chemistry, structural characterization, and data analysis to provide robust solutions, structured feedback, and academic consulting for complex technical projects.
