Postdoc in Geophysics

Deadline: February 10, 2024

We are looking for a Postdoc in Geophysics with experience in the research of complex systems and/or non-linear dynamics and tipping points in the climate system. The Postdoc will perform a unique combination of laboratory experiment and modeling to challenge our understanding of tipping points in complex natural systems.

Niels Bohr Institute

It is currently debated whether we can predict with confidence that abrupt and irreversible climate tipping points are approached. Important recent studies claim to do so, but hinge on key theoretical assumptions that allow for the identification of so-called early-warning signals. These assumptions could so far not be verified in the real world or climate models.

It is the aim of this project to do so with a lab experiment representing the much-feared tipping point of a collapse of the Atlantic meridional overturning circulation.

The Postdoc will perform lab experiments with a model of the thermohaline circulation where the stability and variability of co-existing circulation states is measured as freshwater and temperature gradients of the model basins are varied, as well as for changing heterogeneity in forcing and geometry. The experiments are guided by simulations with ocean and dynamical systems models.

The Postdoc will closely collaborate with our interdisciplinary team at Physics of Ice, Climate, and Earth (https://nbi.ku.dk/english/research/pice), consisting of physicists, oceanographers and climate modelers.

About the applicant

  • Applicants with a background in any of the fields of complex systems science, dynamical systems, climate dynamics, or oceanography are encouraged to apply.
  • Experiences with climate model simulations, time series analysis, and/or fluid dynamics experiments are furthermore appreciated.
  • The postdoc’s duties will include research within Geophysics as well as teaching. The post may also include performance of other duties.

Further information on the Department is linked at https://www.science.ku.dk/english/about-the-faculty/organisation/. Inquiries about the position can be made to johannes.lohmann@nbi.ku.dk.

The position is open from April 10, 2024 or as soon as possible thereafter. The position is for 24 months.

The University wishes our staff to reflect the diversity of society and thus welcomes applications from all qualified candidates regardless of personal background.

Terms of employment

The position is covered by the Memorandum on Job Structure for Academic Staff.

Terms of appointment and payment accord to the agreement between the Ministry of Finance and The Danish Confederation of Professional Associations on Academics in the State.

Negotiation for salary supplement is possible.

The application, in English, must be submitted electronically by clicking APPLY NOW below.

Please include

  • Curriculum vitae
  • Diplomas (Master and PhD degree or equivalent)
  • Research plan – description of current and future research plans
  • Complete publication list
  • Separate reprints of 3 particularly relevant papers

The deadline for applications is February 10, 2024, 23:59 GMT +1.

After the expiry of the deadline for applications, the authorized recruitment manager selects applicants for assessment on the advice of the Interview Committee.
