University of Lausanne

Introduction
The University of Lausanne (UNIL) is a leading international teaching and research institution composed of seven faculties where approximately 17,000 students and 5,000 collaborators, professors, and researchers work and study. Ideally situated on the lake of Geneva, near Lausanne’s city centre, its campus brings together over 120 nationalities. As an employer, UNIL encourages excellence, individual recognition, and responsibility.

Presentation
The Institute of Earth Sciences at the University of Lausanne (UNIL) is seeking to fill three PhD positions in a project funded by the Swiss National Science Foundation. The project entitled Geophysics-assisted Rare Event Estimation in Changing Environments (GREECE) is interdisciplinary in nature and includes project partners with strong expertise in environmental geophysics, hydrology, climate science, data science and statistics. PhD A will develop methodologies for the efficient estimation of rare event probabilities, related to subsurface properties and in the presence of climate change, within an inversion setting. PhD B will develop efficient deep-learning-based surrogate models to replace computationally costly forward solvers in subsurface hydrology and near-surface geophysics. PhD C will generate meteorological time-series that are representative of different climate scenarios and use them together with the methodological advances by PhDs A and B to assess how the probabilities of rare events depend on the chosen process model. PhD C will also explore spatial upscaling of rare event probabilities in subsurface hydrology.

Job information
Expected starting date: 01.01.2025 or a later date to be agreed upon
Contract length: 1 year, renewable up to 4 years
Activity rate: 100%
Workplace: Institute of Earth Sciences, Faculty of Geosciences and Environment, University of Lausanne

Your responsibilities
Work independently and in collaboration with other PhD students and project partners to advance research within the scope of a PhD thesis. Contribute (up to 15%) to teaching or other institutional activities.

Your qualifications
Successful applicants are expected to have a MSc degree in geophysics, hydrology, physics, statistics, data science or engineering. Ideal candidates will have a strong interest in Bayesian statistics (PhD A); machine learning or scientific computing (PhD B); hydrometeorology, subsurface hydrology or soil science (PhD C). A willingness to work closely with the other PhD students and with project partners is expected.

An advanced level in English is needed, while a working knowledge of French is an advantage.

What the position offers you
You will join an institute of 160 members dedicated to research and teaching in the Earth sciences. We offer excellent working conditions in a multicultural, diverse, and dynamic academic environment, with opportunities for professional training and networking. The GREECE project will allow you to exchange with leading research groups both nationally and internationally.
