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.

The Korea Advanced Institute of Science and Technology (KAIST) is a national research university located in Daedeok Innopolis, Daejeon, South Korea.

KAIST is considered to be one of the most prestigious universities in the nation. KAIST has been internationally accredited in business education, and hosts the Secretariat of the Association of Asia-Pacific Business Schools (AAPBS). KAIST has 10,504 full-time students and 1,342 faculty researchers (as of the Fall 2019 Semester) and had a total budget of US$765 million in 2013, of which US$459 million was from research contracts. In 2007, KAIST partnered with international institutions and adopted dual degree programs for its students. Its partner institutions include the Technical University of Denmark, Carnegie Mellon University, the Georgia Institute of Technology, the Technical University of Berlin, and the Technical University of Munich.

HLA is a time signal radio station in Daejeon, South Korea, operated by the Korea Research Institute of Standards and Science. Established on November 24, 1984, it transmits a 2 kW signal on 5 MHz (±0.01 Hz). Originally only transmitted for 7 hours per day (01:00–08:00), 5 days per week (M–F), it is continuous as of 2011.

Korea Research Institute of Bioscience and Biotechnology (KRIBB) is a government research institute in Daejeon, South Korea. It is dedicated to biotechnology research across a broad span of expertise, from basic studies for the fundamental understanding of life phenomena to applied studies such as drug discovery, novel biomaterials, integrated biotechnology and bioinformation. KRIBB was established in 1985. Its accomplishments include the advancement of welfare and medical technology, an increase in food production, a cleaner environment and new bio-materials and energy sources. It has identified reasons for the failure of animal cloning, conducted a comparative study of chimpanzee genes and successfully analyzed the structure of the reactive oxygen species switch protein, which became the first study by Korean scholars to be published in Cell, an international scientific journal. The institute was ranked first in the discovery of new microorganisms, including the indigenous microorganisms of the Dokdo Islets, for four consecutive years. Its recent accomplishments include the development of a genome capable of controlling cancer cell proliferation and the identification of a neuropeptide Y-based growth control mechanism, with possibilities for new treatments for cancer, diabetes, obesity and ageing. Nano–bio sensor research led to the development of the world's smallest surface plasmon resonance biochip.
