1. Purpose and Background
With the vision of “Making Discoveries for Humanity and Society,” the Institute for Basic Science (IBS) was founded in 2011 by the Korean government to promote basic science in Korea. To date, IBS has 31 Research Centers and each Center has been yielding outstanding results in various research fields.
The IBS “Young Scientist Fellowship” started in 2016 to play an active role in fostering the next generation of basic science leaders. We believe this Fellowship offers junior scientists opportunities to conduct independent research by utilizing state-of-the-art infrastructure and to grow on the basis of research collaborations with leading researchers.
We hope that the Fellowship serves as a stepping stone for our researchers to mature into leading researchers in basic science.
Within 7 years of obtaining a Ph.D. (obtained no earlier than 1 January 2013) or under the age of 40 with a Ph.D. (born no earlier than 1 January 1980)
※ Ph.D. candidates must be conferred with Ph.D. degrees before February 28, 2021.
※ Current IBS researchers are eligible to apply, if they meet the above criteria.
3. Recruiting Research Center and Number of Openings
Discrete Mathematics Group has an opening for 1 YSF.
For other centers and groups, please visit the IBS website https://www.ibs.re.kr/ysf/.
※ The final number of openings may change depending on the circumstances of IBS.
4. Benefit and Condition
- Full-time work and 100% research participation in principle
※ If successful candidates have been also selected for another institute’s research project (e.g. Sejong Science Fellowship, Young Researcher Program of National Research Foundation), their selection may be cancelled.
- Annual budget of KRW 150–300 mil. per year, including salary of KRW 60–70 mil. (up to KRW 150 mil. for theoretical fields and up to KRW 300 mil. for experimental fields)
- Appointment for three years with a possible two-year extension depending on the performance review results
※ When current IBS researchers are selected as a Young Scientist Fellow (YSF) of their Center, support will be offered for up to three years. Please refer to the FAQ for details.
- After physically relocated to one of the IBS Centers, YSFs will conduct independent research by utilizing research facilities and equipment of the Center. YSFs may organize a small research group.
- Selected YSFs must be appointed and commence their research within 2021.
※ If their appointment and research commencement processes are not completed within 2021, their selection may be cancelled.

On October 27, 2020, Jeong Ok Choi (최정옥) from IBS Discrete Mathematics Group / GIST gave a talk on some game-theoretic problems on graphs, more specifically on the contagion game and the network creation game. The title of her talk was “Various game-theoretic models on graphs“.
On October 22, 2020, Chun-Hung Liu (劉俊宏) from Texas A&M University gave a talk on his recent work answering several open problems on the asymptotic dimension of several graph classes at the Virtual Discrete Math Colloquium. The title of his talk was “Asymptotic dimension of minor-closed families and beyond“.
On October 21, 2020, Joonkyung Lee (이준경) from University College London gave a talk at the Discrete Math Seminar on norms defined from graphs motivated by Sidorenko’s conjecture and Gowers norms on extremal combinatorics, unifying two seemingly different concepts of real-norming graphs and complex-norming graphs. The title of his talk was “On graph norms for complex-valued functions“. Joonkyung Lee will stay at the IBS discrete mathematics group for several weeks from October 19.
The IBS Discrete Mathematics Group (DIMAG) in Daejeon, Korea invites applications for one postdoctoral research fellowship position.
DIMAG is a research group that was established in December 1, 2018 at the Institute for Basic Science (IBS), led by Prof. Sang-il Oum. DIMAG is located at the headquarters of the Institute for Basic Science (IBS) in Daejeon, South Korea, a city of 1.5 million people.
