Wiem Nefzi Doctor in Applied Mathematics (Statistics)

Présentation

My research focuses on nonparametric estimation on Riemannian manifolds, particularly density and regression estimation for stochastic processes and random fields. I combine theoretical analysis, methodology, and numerical simulations, with experience in teaching and statistical programming (R, Python).
