    THE PERSISTENCE OF SHADOWS: Dreams, Reveries, and Memories in 'The Chandelier' by Clarice Lispector. A Psychoanalytic an
    Feb 2014 - Sep 2016 (2 years 8 months)
    During my Master’s degree in Letters (Literary Theory and Comparative Literature) at the University of São Paulo (USP), I cultivated advanced skills in academic research and critical analysis. I authored a 200-page dissertation centered on the novel "O lustre" by Clarice Lispector, in which I conducted a deep investigation into the protagonist's journey and dreams through the combined lenses of Psychoanalysis and the Theory of Literature. This rigorous academic training provides the foundation for my current expertise in high-stakes linguistic evaluation and the interpretation of complex, multi-layered data sets.
