Bio
I am a fourth and final year Ph.D. candidate in Social Data Science at the University of Oxford where I am supervised by Scott Hale and Ralph Schroeder. I also consult for the World Bank and am affiliated with the Weizenbaum Institute and New York University.
I study online harms in global contexts, combining natural language processing with insights from social science. My research explores how AI can both reduce such harms and create new ones, with a particular interest in cross-geographic disparities in the effectiveness of AI systems at protecting users. To answer these questions, I conduct model evaluation, large-scale data analysis, and experiments, focusing on issues such as hate speech, misinformation, and biases in large language models. My recent work in this area received an Outstanding Paper Award at ACL.
My research is supported by a Global Merit Award from the Shirley Scholars Fund.
