I obtained a Ph.D. and M.Sc. in Natural Language Processing, both earned in Computer Science and Computational Mathematics from the University of São Paulo (USP). I also hold a BS in Information Systems and a BA in Linguistics. During my Ph.D., I was a visiting researcher at the University of Southern California (USC) in the USA and an invited researcher and speaker at the Leibniz Institute for the Social Sciences (GESIS) in Germany. I also received the prestigious Google Latin America Research Award (LARA) fellowship, the Best Thesis Award in Artificial Intelligence, and was recognized by the Brazilian Computer Society for having one of the best theses in Computer Science. In addition, I have actively contributed to ACL and AAAI international conferences and workshops, serving as a program committee member and co-organizing International AAAI Conference on Web and Social Media (ICWSM), Workshop on Online Abuse and Harms (WOAH), and Explainable Deep Neural Networks for Responsible AI (DeepXplain), along with shared tasks [i] [ii] on hate speech. My research focuses on enhancing the interpretability of Language Models (LMs) while ensuring their alignment with safety, factuality, and fairness. I have contributed to efforts addressing hate speech and misinformation in underrepresented communities, and to the development of methods and benchmark datasets that aim to promote transparency and accountability in AI systems.
