Research and professional activities
Research interests
Numerical methods for stochastic processes with application to signal processing, control engineering, economics and physics
Nonlinear filtering and stochastic control
Statistical methods in telecommunications
Information Theory and Information Geometry
I am interested in connections between information theory and statistical mechanics; in particular in the way information flows between interacting systems. This has strong connections with nonlinear filtering and stochastic control. Information geometry provides a natural framework in which to set many of these ideas.
