I am a third-year CS PhD student at Cornell Tech, advised by Emma Pierson. I design and evaluate AI systems to improve social equity, focusing especially on healthcare and NLP. My healthcare work focuses on evaluating fairness (MLHC 2023) and using LLMs to promote equity (arXiv 2023). My NLP work focuses on pluralistic alignment: when do users disagree about what constitutes a “good” language model (EMNLP 2024), and how should pluralism inform model design?
In 2024, I interned with the FATE group at Microsoft Research Montréal. At Cornell, I am part of the Digital Life Initiative and the AI, Policy, and Practice working groups. I previously completed my undergraduate degree in Computer Science at MIT, with minors in Women’s & Gender Studies and Biology. I enjoyed working with the Data + Feminism Lab.
I occasionally write things here. I like food, and I occasionally write food-related things on Substack. I am grateful to all the mentors and collaborators who have helped me along the way; if I can be helpful, I am always happy to chat via email.
