2 Postdoctoral Fellow Positions in Speleothem Research - Busan, South Korea

Busan, South Korea
Term: Full time, 2 years
Start date: March or April 2022.
Location: The IBS Center for Climate Physics (ICCP) is located in Busan, the second largest city in South Korea and the ninth largest port city in the world. Surrounded by the ocean and mountains, the city has a dramatic natural background. From designer cafes, international movie and art festivals, award-winning restaurants to temples at the end of hiking trails, Busan has something to offer for everyone.
The two 2-year postdoctoral fellow positions are funded as part of the IBS Young Scientist Fellowship grant to Dr. Jasper A. Wassenburg at the ICCP in Busan, South Korea.
The IBS Center for Climate Physics (ICCP; directed by Prof. 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 two 2-year postdoctoral fellow positions are funded as part of the IBS Young Scientist Fellowship grant to Dr. Jasper A. Wassenburg. The successful candidates will be working with speleothems from the East Asian Monsoon region with a focus on South Korea. The key objectives of the project are to reconstruct the isotope composition of fossil rainfall from the western North Pacific and reconstruct seasonality by means of speleothem fluid inclusion isotope analysis over the last 125,000 years on the Korean Peninsula. Combined fluid inclusion isotopes, clumped isotope analysis and TEX86 will be used to reconstruct absolute cave air temperatures. Furthermore, the research team will be experimenting with a novel setup to achieve high precision 17O-excess values from speleothem fluid inclusions. The project also involves 230Th/U dating, cave monitoring, carbonate δ13C, δ18O, trace element analysis and climate modeling.
Applicants should have a PhD in Earth Sciences, Geology, Physical Geography, Physics or similar. A strong background in speleothem science, excellent lab and writing skills, fluency in English, and basic knowledge of isotope fractionation are required. Experience with speleothem fluid inclusions is an advantage but not a requirement.
Review of applications will start on December 1, 2021 and continue until the positions are filled. Please submit a cover letter with a motivation of application, a curriculum vitae with publication list, and the names and contact information of 2 references to Ms. Jenny Choi (
