Postdoc position in speleothem paleoclimate research

  • Employer: IBS Center for Climate Physics
  • Location: Pusan National University, Busan, South Korea
  • Education Level: PhD
  • Job type: Postdoctoral Fellow – Assistant Researcher, depending on experience 
  • Salary: 54-65 million KRW/year (~43,000-50,000 USD)
  • Term: Full Time, 2 years, with possibility for renewal

We invite applications for a postdoc position in the speleothem research group at the IBS Center for Climate Physics (ICCP), Pusan National University, Busan, South Korea.

Applicants for this position should hold a PhD in geology, geochemistry, earth science or a related field. Candidates are expected to have a strong geochemical background, extensive lab experience, a good publication record, a high level of independence, curiosity, and an interest in working in an international and interdisciplinary research environment. Experience with Laser-Ablation Inductively Coupled Plasma Mass Spectrometer (LA-ICPMS) systems is desirable.

The successful candidate will work with Prof. Axel Timmermann and Dr. Jasper Wassenburg to reconstruct past climate shifts using high-resolution trace element scans of speleothem samples from Asia (including South Korea) and Africa. The trace element analyses will be conducted on ICCP’s new ASI Resolution-Agilent 7900 system. The candidate will operate and maintain the system, run trace element analyses on a variety of samples, interpret the results in terms of climate and soil processes and publish the results in excellent scientific journals.

The ICCP speleothem team is equipped with a Kiel device coupled to a MAT253+ for stable oxygen, carbon and clumped isotopes, a Picarro L2140i for fluid inclusion isotopes, an LA-ICPMS, an LGR Water isotope analyzer and a DeltaQ IRMS with gasbench (delivery on 2023).

The ICCP (, directed by Dr. Axel Timmermann, is dedicated to advancing the understanding of natural climate variability, man-made climate change and their impacts on the hydrological cycle, regional processes, ice-sheets, and sea level. The ICCP is generously funded through the Institute for Basic Science (IBS) (
