Eve Fleisig

PhD student at UC Berkeley | Ethical NLP

I'm a third-year PhD student at UC Berkeley, advised by Dan Klein. My research lies at the intersection of natural language processing (NLP) and AI ethics: how can we create NLP systems that we trust to work for all users, without perpetuating societal harms? Specifically, I have worked on measuring & mitigating harms in text generated by language models, improving evaluation, and training models that account for different user perspectives or data annotators who disagree.

I did my undergraduate work at Princeton University, advised by Christiane Fellbaum, where I worked on the psycholinguistics of bilingualism and fairness in NLP.

My research is supported by an NSF Graduate Research Fellowship.
