Biography

I hold a Ph.D. in Computer Science and Computational Mathematics from ICMC - University of São Paulo (USP). Currently, I am a researcher at BIFI at the University of Zaragoza in Spain, where I am affiliated with ARAID. Among my most outstanding achievements, I was awarded the best Ph.D. thesis in Brazil, CAPES Thesis Award Edition - 2020, in computer science. My primary research interests include models of real-world systems through network science, data analysis, natural language processing, and machine learning.
