I’m a national security journalist in New York focused on the Asia-Pacific. I work at The New York Times on the Opinion page, where I was part of the team named Pulitzer finalist for “At the Brink,” a series on the nuclear threat. I also reported for “Overmatched,” a series on how the American military is unprepared for a protracted war.

Previously, I reported on the United States for The Asahi Shimbun, Japan’s second-largest paper. I received a bachelor’s in history from Columbia University and master’s from The University of Tokyo.
