I am an assistant professor in the Center for Social Data Science at the University of Copenhagen (). I am currently also a visiting researcher with the RIKEN Center for Computational Science (Japan). My main research area is Natural Language Processing, in particular model analysis and evaluation of natural language understanding systems.

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 meaning representations. I hold a Ph.D. degree from the Department of Language and Information Sciences at the University of Tokyo (Japan).
