About

I am a Ph.D. candidate at the University of Maryland, College Park in the Department of Computer Science advised by Prof. Hal Daumé III. My current research focuses on fairness in NLP, human-AI interaction, and their intersection. More broadly, I am interested in fairness and trust/reliance in AI systems. Some questions that I ask in my research are:

  • When people interact with a model exhibiting certain biases (or even a "debiased" model), what are the tangible effects/harms on the person?
  • When people work together with a model to make decisions, how can we encourage outcomes that are more fair to the people affected by these decisions?

Previously, I did a combined BS/MS in Computer Science (with a secondary major in Japanese Studies and a concentration in AI) at Case Western Reserve University, advised by Prof. Soumya Ray.
