Research interests
The focus of my research is algorithmic fairness. I have worked on notions of algorithmic fairness for IR, introducing a method to balance the visibility of different groups based on a statistical test on rank prefixes, requiring a complex algorithm to account for multiple hypothesis tests that are not independent. Later, we sought an in-processing method applicable within a learning to rank paradigm. I also worked on automated risk assessment methods that satisfy algorithmic fairness criteria, such as separability and sufficiency, validating them through interdisciplinary research in two distinct settings: university admission policies and criminal recidivism prediction.
