Jae Kyoung Kim

Also known as Jaekyoung Kim, Kim Jae-kyoung, 김재경

Jae Kyoung Kim is a mathematician at KAIST who applies dynamical systems, scientific machine learning and AI to sleep and circadian biology. After a Michigan PhD and a postdoctoral fellowship at Ohio State's Mathematical Biosciences Institute, he joined KAIST's Department of Mathematical Sciences in 2015 and launched the IBS Biomedical Mathematics Group in 2021. His team released the SLEEPS sleep-disorder algorithm in 2023, and its personalized sleep guide reached Galaxy Watch 8 users in 2025. He received the Choi Seok-jeong Award in 2021 and an Innovation Award at KAIST Research Day in 2026. He is an associate professor of mathematical sciences at KAIST and Chief Investigator of the IBS Biomedical Mathematics Group.

From the biography.

  1. The United States employs an estimated 48% of people shaping AIIncludes KAIST. We estimate where the people shaping AI work today, how universities, companies and research institutes split across countries, and how country shares have changed since the 1960s.
  2. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes KAIST. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  3. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes Korea University. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  4. 44% of AI career moves go from one university to anotherIncludes KAIST. We estimate how 26,439 AI career moves link universities, companies, labs, nonprofits and government research centers, with decade counts, net flows and the top paths.
