The Research Center for Applied Sciences (RCAS) is a dedicated unit within Academia Sinica, Taiwan, focused on mission-driven scientific applications. The establishment of the RCAS was based on the idea of the then President of Academia Sinica, Yuan-Tseh Lee, that "the Central Academy of Sciences should go out into the community," and a consensus was reached after many meetings with academicians of the Mathematics and Science Group, as well as with industrial, governmental, and academic organizations in Taiwan. Prior to amendments to the Academia Sinica Organic Law, the "Institute for Applied Science and Engineering Research Preparatort Office" was established in 1999. Following the amendment approval in 2003 and subsequent presidential approval, it officially became the "Research Center for Applied Sciences" in 2004. The center functions as a diverse hub incorporating multiple specialized research centers. It aims to continuously engage outstanding researchers from both internal and external domains, establish large-scale core process laboratories, and conduct significant interdisciplinary research in the future.
