Research Fellow (Petrology & Tephrostratigraphy)

The Earth Observatory of Singapore (EOS) and the Asian School of the Environment (ASE) invite applications for a Research Fellow in Petrology and Tephrostratigraphy to participate in the reconstruction of the eruptive history of Sumatra (Indonesia) with a particular emphasis on large explosive (caldera-forming) eruptions. This will involve field work for site selection and collection of sediment cores from lakes and/or peatbogs, identification of tephra layers followed by their geochemical and petrological analysis, sample dating by radiocarbon or Ar/Ar methods, and correlations with ignimbrites from calderas in Sumatra.
The successful candidate will work in a vibrant scientific department with a team of international scientists. Candidates with prior experience in tephrostratigraphy and petrology are desired. Commencement date is in January 2018, the position is for 2 years.

Duties & Responsibilities: 

Field work: The candidate will work effectively with local collaborators and assist with site selection, field work planning and execution for the collection of sediment cores.
The candidate will log the collected sediment cores, and identify and sample tephra layers preserved within them
Correlations of tephra with specific eruptions: The candidate will texturally and geochemically characterize the sampled volcanic ash. He or she will use statistical methods to correlate tephra layers between cores and with known eruptions
The candidate will be expected to publish the scientific outcomes of this research in high quality, peer-reviewed, international scientific journals
Involved with PhD student mentoring
Participate in the various volcanology-related education and outreach activities of the EOS


• Prior experience in tephrostratigraphy and petrology
• Using geochemical laboratory facilities (e.g. XRF core scanner, scanning electron microscope, electron microprobe, and laser-ablation ICP-MS)
• Conducting fieldwork for research


PhD degree in volcanology or equivalent
