about me

I am currently a senior researcher at Microsoft based in Redmond. I did my postdoc at the Manning College of Information & Computer Sciences, University of Massachusetts Amherst working with Prof. Mohit Iyyer.

I hold a Ph.D. from the Department of Language and Information Sciences at the University of Tokyo.

research

I am interested in how well natural language processing (NLP) systems handle long-form content, both as input and output. My work includes areas like machine translation of creative texts, story generation, summarizing long texts, verifying claims about book-length content, and multilingual long-form question answering.
