Low-mass pre-main-squence (PMS) stars, aged of a few millions years are called T Tauri stars (TTSs). They often show a strong magnetic activity generating photometric and velo- cimetric (radial velocity / RV) fluctuations that reduce our chance to de

The calibration of a computer code consists in the comparison of its predictions to the experimental data, so that the best input parameter values can be inferred. We work in a Bayesian framework, where the parameters are treated as random variables

We study in this thesis the asymptotic behavior (almost-sure, in distribution, on average) of the random variable counting the number of zeros of random trigonometric functions on a given interval. We specifically investigate the universality phenome

This manuscript focuses on Bayesian modeling of unknown functions with Gaussian processes. This task arises notably for industrial design, with numerical simulators whose computation time can reach several hours. Our work focuses on the problem of mo

Metamodels are widely used in industry to predict the output of an expensive computer code. As industrial computer codes involve a large amount of input variables, creating directly one big metamodel depending on the whole set of inputs may be a very

The context of this thesis is the inference for partially observed epidemic dynamics. The development of approaches for estimating parameters of these dynamics from observations of their follow-up is a first important challenge, but difficult from a

To understand and to be able to forecast natural phenomena is increasingly important nowadays, as those predictions are often the basis of many decisions, whether economical or ecological. In order todo so, mathematical models are introduced to repre

Collective motions describe populations in which individuals' interactions are the driving force behind their displacements and their transformation over time. Understanding and controlling collective motions are significant issues in many fields, es
