Research Interests

Directional statistics

The topic of directional statistics is concerned typically with observations which are directions (unit vectors in Rp), axes (lines through the origin of Rp), or rotations of Rp. More generally, observations can be points in a compact Riemannian manifold.

A famous data set on the rotation group SO(3) is the set of vectorcardiogram data of Downs, Liebman and Mackay (1971).

One of the main techniques in directional statistics is that of embedding the sample space in a suitable Hilbert space.

Differential geometry of parametric inference

Asymptotic expansions can be expressed efficiently in the language of differential geometry. The invariant quantities which arise have geometric interpretations and provide a way of taming complicated expansions.

Quantum stochastics

Every measurement on a quantum system gives rise to a probability distribution on the outcome space. Thus measurements transform families of quantum states into families of probability distributions.
