We are hiring! The IBS Discrete Mathematics Group (DIMAG) Research Fellowship (Due: December 3, 2025)

The IBS Discrete Mathematics Group (DIMAG) in Daejeon, Korea invites applications for four research fellowship positions (senior researcher positions).

DIMAG is a research group that was established on December 1, 2018 at the Institute for Basic Science (IBS), led by its Chief Investigator (CI) Sang-il Oum. DIMAG is located at the headquarters of IBS in Daejeon, South Korea, a city of 1.5 million people. Currently, DIMAG consists of researchers from various countries and the work is done in English. DIMAG is co-located with the IBS Extremal Combinatorics and Probability Group (ECOPRO).

Successful candidates for the research fellowship positions will be new or recent PhDs with outstanding research potential in all fields of Discrete Mathematics with emphasis on Structural Graph TheoryExtremal Graph TheoryCombinatorial OptimizationMatroid Theory, and Algorithms.

This appointment is for about two years, and the starting salary is no less than KRW 63,000,000. The appointment is one-time renewable up to 5 years in total, contingent upon the outstanding performance of the researcher. The expected appointment date is September 1, 2026, and it can be adjusted to earlier or later, but no later than December 1, 2026. This is purely a research position and will have no teaching duties. However, if desired, successful candidates may have the opportunity to teach at KAIST.

A complete application packet should include:

2. Curriculum vitae including a list of publications and preprints (PDF format)

3. Research statement (PDF format)

4. Consent to Collection and Use of Personal Information (form available on the application page)

5. 3 recommendation letters

For full consideration, applicants should upload items 1, 2, 3, and 4 on the application website (https://dimag.ibs.re.kr/apply) and arrange their recommendation letters to be submitted directly by the letter writers through the link sent via email during the online application process by December 3, 2025, Wednesday (Anywhere on Earth (AoE)). Recommendation letters submitted by an applicant will not be considered. DIMAG encourages applications from individuals of diverse backgrounds.

For Korean citizens who have not yet completed their military duty: 전문연구요원 종사를 희망하는 경우에는 지원 의사와 병역 관계를 cover letter 및 이메일 등에 표시하여 제출 필요. 다만 현역입영대상자의 전문연구요원 신규 편입은 불가하며, 보충역 대상자 및 타 기관에서 전직해서 오는 경우에 한하여 지원 가능(전직 요건이 충족 되어야만 함)
