Open positions

We’re hiring! New positions open to join the ICE team:

In the framework of a newly-funded project by the Swiss National Science Foundation entitled “Reconciling geological and modelled reconstructions of Alpine glacier evolution from the Last Glacial Maximum into the Holocene”, we are looking to fill 1 PhD and 1 2-year-long PostDoc positions at the University of Lausanne (UNIL, ICE group,, as well as 1 PhD position at the University of Zurich (UZH, 3G group,, Switzerland.

Project summary: Quaternary glaciations have left numerous geological footprints in the landscape of the European Alps, especially during and after the Last Glacial Maximum (LGM). Despite extensive field evidence and dating constraints, the chronology of the glacier evolution is far from being well understood. Numerical models accounting for the glacier thermo-dynamics, climate and mass balance have proven to be promising tools for simulating ice extent evolution and fill knowledge gaps. However, existing models generally show significant biases with geomorphological reconstructions.  These discrepancies between field- and model-based reconstructions is in good part due to spatially too coarse models that do not resolve the complex relief of the Alps. Unfortunately, traditional ice flow models are computationally too expensive to achieve the resolution required over timescales of several tens of millennia. To overcome this bottleneck, the goal of this project is adopt a new modelling strategy using Instructed Glacier Model (IGM, — a new glacier model accelerated by deep-learning. This project at the interface of glacier modelling and Quaternary geology aims i) to further develop IGM to include relevant physical processes (such as thermo-mechanics, sediment transportation, moraine production …), ii) to integrate new geological records (such as trimlines, dated moraines sequences, erratic boulders, etc.). Ultimately this project aims to produce a well constrained high-resolution transient reconstruction of ice extent over the Alps and enhance our ability to interpret the palaeo record and our understanding of the spatio-temporal response of glaciers to climate variations from the LGM through the Holocene.

Roles and candidate profiles: The PhD based at UNIL will focus at modelling the period until LGM, while the the PhD based at UZH will focus at modelling the post-LGM period until the Holocene. The PostDoc (based at UNIL, working in strong collaboration with UZH) will be responsible for setting-up the model (developments and assimilation of field data). Candidates for the PhD position will have a master degree either in Earth sciences, geology, geophysics, physics, physical geography, geosciences, applied mathematics, computer sciences, or a related field, and should have a sharp interest in numerical modelling and its application in the geosciences (here involving glaciology, Quaternary geology, and paleo climate). Candidates for the Postdoc position will have prior expertise in glacier modelling and/or in Quaternary geology. Previous experience in numerical modelling and Python programming is an asset. Good writing and communication skills in English as well as the motivation to fruitfully collaborate with the research groups in Lausanne and Zurich and in an interdisciplinary framework are essential.

If you wish to apply, please send a cover letter, CV, and references within a single pdf file to the project PIs: Guillaume Jouvet (,  Andreas Vieli ( and Samuel Nussbaumer ( A first review of application will start on December 1st, and will continue until all positions are filled.
