I am an assistant professor in the Computer Science Department at the IT University of Copenhagen (). My main research area is Natural Language Processing. I am currently a co-program-chair of ACL 2023.
Before moving to Denmark, I was a postdoctoral research associate in the University of Massachusetts, working with Anna Rumshisky on sentiment analysis, question answering and analysis of Transformer-based language models. Then I was a postdoctoral associate and assistant professor at the Center for Social Data Science at the University of Copenhagen, focusing on AI and society. I hold a Ph.D. degree from the Department of Language and Information Sciences at the University of Tokyo (Japan).
