We are hiring! Senior Research Fellow Position at the IBS Discrete Mathematics Group
The IBS Discrete Mathematics Group (DIMAG) in Daejeon, Korea invites applications for one senior research fellow position.
DIMAG is a research group that was established on December 1, 2018 at the Institute for Basic Science (IBS), led by Chief Investigator, Dr. Sang-il Oum. DIMAG is located at the headquarters of IBS in Daejeon, South Korea, a city of 1.5 million people.
Website: https://dimag.ibs.re.kr/
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 this position are expected to have research experience in Discrete Mathematics, in particular in Structural Graph theory, Combinatorial Optimization, Matroid Theory, and Algorithms, for 10 years or more after their Ph.D.’s.
The appointment is initially for two years and can be extended further after reviews of the research performance until the group’s closure or the retirement age.
The starting annual salary is no less than KRW 96,000,000, if the successful candidate has 10 years or more research experience after Ph.D.’s.
The expected appointment date is June 1, 2025, and it can be adjusted to earlier or later, but no later than September 1, 2025. This is purely research position and will have no teaching duties.
A complete application packet should include:
• AMS standard cover sheet (preferred) or cover letter (PDF format)
• Curriculum vitae, including a list of publications and preprints (PDF format)
• Research statement (PDF format)
• Consent to Collection and Use of Personal Information & Application for the IBS (PDF file)
For full consideration, applicants should email all the items to dimag@ibs.re.kr by August 19, 2024, 18:00 KST.
DIMAG encourages applications from individuals of diverse backgrounds.
Suggested E-mail subject from applicants: [DIMAG – name]
e.g., [DIMAG – PAUL ERDOS]
