The Institute for Research and Academic Services (IRAS), originally named as the Center for Research in Business or CRIB, has been serving Thai business community and international corporations by offering a wide range of research services since its inception in 1982 by Dr. Federic L. Ayer, the first Vice President for Research Affairs.

        CRIB achieved continuing growth and expansion in meeting the ever-increasing demands for its services. Under the supervision of Dr. Jirawat Wongsawadiwat the present Vice President for Research Affairs, CRIB has been conducting research projects in social sciences since 1991. In 1993 an additional entity was created and CRIB was renamed as Center for Research in Business and Social Sciences (CRIB & SSc). This additional initiative was intended to meet the demands for research in social sciences. Over time these demands have risen hand in hand with the growth of Thailand's economy and its status. In 2013, the AU merged Research Institute of Assumption University and ABAC Poll Research Center together, and later in 2014 it was renamed as Institute for Research and Academic Services (IRAS). In compliance with the University’s policy and strategic plan, IRAS has moved under the direct jurisdiction of the Vice President for Academic Affairs since November 1, 2021.
