In this contemporary era, the movement of people across national borders has accelerated. In the Western countries such European countries and the United States of America, immigration, including refugees, has become a serious issue of contention that heavily influences the party politics. The countries in Asia have also begun to seriously consider immigration issues due to their aging society as well as outbreaks of civil wars in the region.

Under this global situation, my research focuses on public attitudes of host country natives on immigrants and refugees as well as determinants of immigration and refugee policies adopted by host country governments. I further study the interplay between domestic public opinion and immigration policymaking. In particular, I am interested in investigating how people’s political values and feelings toward immigrants and refugees change by analyzing data gathered from originally designed survey experiments in either a single-country or cross-national setting. Moreover, my research utilizes cross-national observational data in order to unravel how different political factors (e.g., political systems) and historical backgrounds (e.g., conceptualization of nationhood) affect immigration and refugee policies across countries.
