Research activities at ISEAS are carried out by a core group of researchers grouped under three research programmes — Regional Economic Studies (RES), Regional Social and Cultural Studies (RSCS), and Regional Strategic and Political Studies (RSPS).
The Director, assisted by the Deputy Director, oversees the work of more than 28 researchers comprising senior fellows, fellows and research associates. Besides group and individual research, the researchers function as coordinators and organisers of research projects, conferences, public lectures and seminars; editors and referees of ISEAS journals, working papers, and book publications.
Researchers provide briefings for the diplomatic community, visiting policymakers, regional academic and policy advisory bodies, the business community and national institutions in Singapore. They also oversee visiting researchers and scholars.
