The National Institute for Mathematical Sciences (NIMS; Korean: 국가수리과학연구소) is a Korean government-funded mathematics research institute. Their work focuses both basic research and applied mathematics with industrial and medical applications. Founded in 2005, NIMS became an affiliated research institute of the Institute for Basic Science in 2012. After delays for multiple years, relocation is planned for late 2023. The vision of NIMS is to "attain a global top 10 competitiveness in industrial mathematics research by 2028".

Daedeok Innopolis, formerly known as Daedeok Science Town, is the research and development district in the Yuseong-gu district in Daejeon, South Korea. The plan to concentrate research institutes and universities was made in 1967 and president Park Chunghee approved subsequent master planning in 1973. Now the district contains over 20 major research institutes and over 40 corporate research centers. There are 232 research and educational institutions to be found in Daejeon, many in the Daedeok region, among them the Electronics and Telecommunications Research Institute and the Korea Aerospace Research Institute. A number of IT venture companies have sprung up in this region due to the high concentration of Ph.Ds in the applied sciences. Korea has invested heavily in building up the research expertise for over 30 years, creating long-term research programs. Over 7,000 PhD researchers are in the sciences in Daedeok and it had the most application for patents during 2000–2011 among the National Industrial Complex. The "town" will provide a core for the International Science and Business Belt. The Daedeok Innopolis logo was created by the industrial design company INNO Design in Palo Alto, USA.

Daejeon Convention Center, also known as simply DCC is the convention center run by the Daejeon Tourism Organization and the sole convention center for the city.

Taejon Expo '93 was a three-month international exposition held between Saturday, August 7, 1993 and Sunday, November 7, 1993 in the central South Korean city of Daejeon (at the time spelled "Taejŏn").

Expo Science Park (Korean: 엑스포과학공원) is a science park in Yuseong District, Daejeon, South Korea, built for Taejŏn Expo '93. Facilities at Expo Park included a garden, amusement park, and observation tower. While the tower and some buildings remain, most of the expo buildings have now been removed. The Daejeon Convention Center became the first convention center in the city in 2008 and opened their second building in 2022. In September 2014, the Ministry of Science, ICT and Future Planning announced that Expo Science Park would be demolished in stages from November 2014 to August 2015. However, in recognition of their historic value, Hanbit Tower, the international conference room, and the simulation pavilion would be kept. In November 2014, the Shinsegae consortium won a bid to build the science complex within the park.In September 2017, Studio Cube, a state-run film studio complex on the site of the park, formally opened its doors to film and drama production.As of 2018, the site is hosting the headquarters complex for the Institute for Basic Science.In August 2021, the 2nd Expo Bridge, connecting the park with Seo-gu, opened.

The Institute for Basic Science (IBS; Korean: 기초과학연구원) is a Korean government-funded research institute that conducts basic science research and relevant pure basic research. IBS was established in November 2011 by the Lee Myung-bak administration as a research institute, later be a core of the International Science and Business Belt (ISBB) upon relocation of their headquarters from a rented property to their own campus in January 2018 using land reclaimed from the Taejŏn Expo '93 in Expo Science Park. Comprising 30 research centers with 68 research groups across the nation and a headquarters in Daejeon, IBS has approximately 1,800 researchers and doctoral course students. Around 30% of the researchers are from countries outside of South Korea. The organization is under the Ministry of Science and ICT. In 2011, the Korean government announced an investment of more than 2 trillion KRW (roughly US$2 billion) to build a heavy ion accelerator facility, named RAON, in northern Daejeon by 2021 before getting pushed back to 2025. The facility is expected to be the world's first device using both the isotope separator on-line (ISOL) and in-flight (IF) methods.From December 2018, the IBS Center for Climate Physics, headed by Axel Timmermann, began to utilize a 1.43-petaflop Cray XC50 supercomputer, named Aleph, for climate physics research. In that same year it was noted that the largest share of Clarivate Highly Cited Researchers in Korea are affiliated with IBS.
