Research
My research develops frameworks and computational methods for studying fairness and inequality in decision-making systems, both algorithmic and human. I work across a range of domains, including healthcare, lending, and criminal justice.
A Profit-Based Measure of Lending Discrimination
We introduce a profit-based measure of lending discrimination in loan pricing and apply it to approximately 80,000 personal loans from a major U.S. fintech platform.
