Host and Sponsors
Hong Liu is moving to IBS as a Chief Investigator to start the IBS Extremal Combinatorics and Probability Group (ECOPRO) on April 2022 and is hiring up to 5 postdocs in all fields of combinatorics with emphasis on extremal and probabilistic combinatorics, graph theory, Ramsey theory, combinatorial number theory and discrete geometry
We are very excited to learn that Prof. Hong Liu from University of Warwick, UK will move to the Institute for Basic Science (IBS) as a Chief Investigator (CI) to lead a new group called the Extremal Combinatorics and Probability Group (ECOPRO) on April 2022. This new group will be also located in the IBS headquarter and is expected to work closely with the IBS Discrete Mathematics Group (DIMAG). Both DIMAG and ECOPRO belong to the IBS Center for Mathematical and Computational Sciences together with the Data Science Group and the Biomedical Mathematics Group and we share the staff members.
The website was made recently. https://www.ibs.re.kr/ecopro/
Yesterday, the IBS Extremal Combinatorics and Probability Group (ECOPRO) posted the hiring announcement for up to 5 postdocs. Here are a few paragraphs from the announcement.
The Extremal Combinatorics and Probability Group (ECOPRO) at the Institute for Basic Science (IBS) in Daejeon, South Korea invites applications for 5 postdoctoral research fellowship positions. ECOPRO is a new research group that will be officially launched in April 1, 2022 at IBS, led by Prof. Hong Liu. We welcome highly motivated postdoc researchers with outstanding research potential in all fields of combinatorics with emphasis on extremal and probabilistic combinatorics, graph theory, Ramsey theory, combinatorial number theory and discrete geometry. This appointment is for 2 years with possible 1 year extension contingent upon the outstanding performance of the researcher. The starting salary is no less than 57,000,000 KRW (about 48,400 USD or 42,800 EUR). The appointment starting date is flexible: between April 1 and Oct 1, 2022. This is a purely research position and will have no teaching duties.
A complete application packet should include
- Curriculum vitae including a publication list (PDF format)
- Research statement (PDF format)
- Up to 3 best papers or preprints
- Consent to Collection and Use of Personal Information (Please convert to a PDF file)
- Two or three recommendation letters.
For full consideration, applicants should email items 1, 2, 3, and 4 and arrange their recommendation letters emailed to ecopro@ibs.re.kr by January 14, 2022.
Recommendations letters forwarded by an applicant will not be considered.
