More specifically, he publishes articles on American use of force (e.g. "Determinants of multilateralism in US use of force: State of economy, election cycle, and divided government" Journal of Peace Research 42:5) and its coalition of the willing (e.g. "When Are Democratic Friends Unreliable? The Unilateral Withdrawal of Troops from the Coalition of the Willing'" Journal of Peace Research 46:2). He also has some works on nuclear proliferation and mass political killing.

Currently, he is a Principle Investigator of the project called CROP-IT (Collaborative Research on Political Information Transmission) funded by Japan Society for the Promotion of Science, and conducts scientific research on Public Diplomacy. His recent study with co-authors appeared in Political Communication ("To Denounce, or Not To Denounce: Survey Experiments on DiplomaticQuarrels"), which also turned into a Washington Post Monkey Cage article in 2016 ("Why Putin and Obama use fighting words when they don’t want to fight"). He was appointed a PRIO Global Fellow from 2017.
