Benoit Nieto

Postdoctoral researcher in Applied Mathematics - Paris, France

Biography

Since October 1, 2024, I am a postdoctoral researcher under the supervision of Emmanuel Gobet at the Center for Applied Mathematics (CMAP) at École Polytechnique, Paris, France.
 

My main research topics are centered around stochastic analysis and statistics of diffusion processes:

  • Stochastic Analysis : Hitting times density, local time, SDEs with singular coefficients, strong     existence and uniqueness.

  • Statistics of diffusion process: Likelihood, Quasi-Likelihood, CLT, Mixing, Test.

  • Analysis : Spectral decomposition, Parabolic cylinder function.
