The Center for Theoretical Physics of the Universe, Cosmology, Gravity, and Astroparticle Physics Group (CTPU-CGA) at Institute for Basic Science (http://www.ibs.re.kr/ctpu-cga), South Korea, invites applications for senior researcher positions in Theoretical Cosmology, Gravity and Astro(particle) physics, which can start before December 16th, 2026 as long as all requirements are met at the point of starting time.* The position can preferably begin from October 1st, 2026 though earlier appointment is negotiable. Any field and/or topic is welcome as long as it is related to cosmology, gravity, and (astro)particle physics. For example, observational cosmology, dark matter, neutrino physics, quantum information, and so on are also welcome in addition to standard theoretical cosmology, gravity, and particle physics.

We recently initiated a new center called CTPU-CGA in CTPU led by the director, Masahide Yamaguchi, from March 2023. We will jointly organize the CTPU with another center CTPU-PTC led by the director, Kiwoon Choi, but the budget, organization, and recruitment are completely independent. The official language at the center is English. Research interests of our group cover broad areas of theoretical cosmology, gravity, astroparticle physics, and related areas. Applications should include CV(see the detailed requirement), publication list, research statement, Consent to Collection and Use of Personal Information / Application for IBS (download on IBS job Board), and at least three letters of recommendation. For full consideration, application materials including the letters should be submitted by December 14th, 2025, through Academic Jobs Online. Dr. Yusuke Yamada has recently joined our group under the Young Scientist Fellow (YSF) program. Accordingly, we are also recruiting a researcher affiliated with YSF. If your research topic is close to that of Dr. Yusuke Yamada, you may be considered for a position affiliated with YSF. Status and all other working conditions are essentially the same. Please select which position you are appying for. You can not apply for both.

You can download Consent form & Application for the Institute for IBS file and find out more information from the below link IBS job Board: https://ibs.re.kr/prog/recruit/eng/sub04_01/view.do?pageIndex=1&searchCondition=&searchKeyword=&idx=1995

* Up to 3 months deferral is negotiable, but doctoral degree must be obtained before December 16th, 2026, even in that case. ** Though the official title is “Senior” Researcher, it’s just an official one. This recruitment is effectively for postdoctoral researchers including fresh ones. ** The term can be extended once, and the additional term is 1 year. A researcher with an exceptionally good performance might get a longer additional term. (The additional term cannot exceed 3 years)
