Hello! I am a CS Ph.D. student at University of California, Irvine (UCI), supervised by Padhraic Smyth and Sameer Singh. my research focuses on the responsible use of generative-based language models (LM) for natural language tasks.

Prior to joining UCI, I worked as a research data scientist at the Responsible AI (FATE) group at Feedzai, under the direction of Pedro Saleiro. There, my research focused mostly fairness, explainability, and reproducibility aspects of Machine Learning (ML) pipelines in the context of credit fraud.

I am currently interested in Responsible AI challenges both for tabular and textual datasets, with a high emphasis on the practical implications for the different personas involved in-the-loop. I am also broadly interested in multi-objective optimization and model analysis/evaluation. My work is supported by a CS Department Excellence Fellowship and a Fulbright fellowship.
