Probability and Mathematical Statistics
Research interests
- Stochastic processes connected to risk theory and to stochastic modelling in finance. Large deviations, with applications to simulation and to numerical methods in risk theory and finance; ruin probabilities for complex models and variance reduction for their computation by simulation, in particular for long memory or heavy tail models; Monte Carlo methods for the pricing/hedging of options via Malliavin calculus techniques.
- Isotropic random fields. Characterizations, harmonic analysis, connections with representation theory, high frequency asymptotics.
- Stochastic modelling and statistics in biology and medicine. First passage times and inverse problems. Methods and models in medical statistics. Modelling and statistics of disease spread.
- Filtering. Filtering with delayed data; non linear filtering and applications to partially observed queues model estimation; high frequency data models and estimates.
- Statistical inference on stochastic processes and random fields. Spectral analysis of stationary and nonstationary processes, long memory, cointegration and fractional cointegration; statistics of spherical random fields, higher order angular power spectra, spherical wavelets, application to cosmological data.
- Random processes on random structures. Random walks in random environment, spatial random graphs, particle systems and hydrodynamic limits, stochastic homogenization, mixing time.
- Statistical learning. Generalization, scalability, dimension reduction, neural networks, kernel methods, multiscale methods, wavelets.
