I am interested in probability theory, in its interplay with analysis and geometry and in problems arising from AI and ML. Particularly I am interested in:
the Schrödinger Bridge Problem (SP) and its relationship with (Entropic) Optimal Transport,
Optimal Transport point of view in (Diffusion) Generative Modelling,
Random Fields and their relation with ML/GenAI,
stochastic optimal control problems: long-time behaviour and exponential ergodicity,
high-dimensional probability.
