I am interested in monitoring and modelling the space-time evolution of different Earth surface processes at high resolution. I mostly focus on local environments (few square kilometers) and on short time scales (minutes to days). In this context, a primary topic is the joint development of in-situ instruments, field acquisition procedures and data processing methods to capture as precisely as possible the natural process of interest. A secondary topic is the use of remote sensing data to complement or validate these in-situ observations.

I apply the developped frameworks to different natural objects such as rain fields, landslides or glaciers.


At the University of Lausanne, I am working more specifically on stochastic rainfall modelling. My main goal is therefore to develop a stochastic model able to reproduce the space-time behavior of rainfall as observed at very high resolution (100m in space, 1min in time). In parallel I am interested in the influence of the regional climate on the observed space-time structure of local rain fields.
