Introduction
UNIL is a leading international teaching and research institution, with over 5,000 employees and 17,000 students split between its Dorigny campus, CHUV and Epalinges. As an employer, UNIL encourages excellence, individual recognition and responsibility.

Presentation
The Institute of Earth Surface Dynamics (IDYST) at the Faculty of Geosciences and Environment is opening one PhD position in the GAIA Lab, in collaboration with the Expertise Center for Climate Extremes.

Job information
Expected start date in position : 01.11.2025 or upon agreement
Contract length : 1 year, renewable 2 × 2 years, maximum 5 years
Activity rate : 80%
Workplace : Institute of Earth Surface Dynamics, Faculty of Geosciences and Environment (FGSE), University of Lausanne (Mouline, Building Géopolis)

Your responsibilities
Precipitation is one of the most important environmental parameters as it impacts the water cycle, ecosystems, the state of natural resources, and the occurrence of natural disasters such as floods, droughts and landslides. However, it is also one of the most difficult quantities to measure in environmental systems. The high spatial and temporal variability, the uncertainty of measurement methods, and the sensitivity to climate change all call for new measurement approaches and models that account for new data types.
The goal of this PhD project is to develop innovative ways of characterizing rainfall events. This will be achieved by using and improving spatio-temporal statistical models that have been developed in the GAIA lab at UNIL. The project will benefit from several years of data from a high-density network of rain gauges deployed in Lausanne.
The aim is to better characterize extreme rainfall events and their effects (in particular floods) in urban contexts and beyond. The research may also relate to studying the impacts of extreme rainfall, for example using urban flood modelling.
A minimum of 50% of the working time will be dedicated to research towards PhD; the remainder of the working time will be devoted to teaching and other institutional activities.

Your qualifications
Applicants should be committed to and enthusiastic about conducting a PhD thesis on the development of statistical models that relate the physical processes underlying rainfall and statistical properties of the precipitation observations. The chosen candidate will have a master’s degree in geosciences, climatology, mathematics, physics, computer science, civil engineering, or a related domain. A requirement for this position is a good base in applied mathematics and programming, demonstrated through academic works (e.g. MSc thesis and/or publications). Knowledge in geostatistics or machine learning, experience in handling remote sensing or climate datasets are advantages.
Candidates should be prepared to develop and use advanced numerical methods, such as geostatistics and machine learning.
Proficiency in written and spoken English is required. Knowledge of French is preferred, but not essential.
