Presently, I am particularly interested in a number of things:

Modern microscopy
enables cell biologist to obtain high resolution 3D images of the
cell nucleus. We are especially interested in the spatial
configuration of sub-nuclear bodies, and the relationship of
configuration to function. This raises new challenges for imaging
and analysis. Some recent work

This is on-going collaboration

Freemont and Dave Stephens.
Advances in data acquisition technology have enabled the continuous
collection of data in a variety of contexts, notably sensor
networks. Such contexts require data analysis algorithms that operate
with a single view of each data item, and the have the capacity to adapt to
changes in the underlying stochastic mechanism. Some recent work

Much of this work was partially supported by the ALADDIN project.
Classification problems are ubiquitous, and are a good example of the
effectiveness of Statistics in the real world. I am especially
interested in complicated contexts, like credit card fraud detection. Outputs

Data mining involves various types of analysis on large data
sets. We have been involved in defining the sub-area of "pattern
detection and discovery", concerned with finding small local
structures in large data sets. Some work in this area includes

Detection and Discovery' Proceedings of the ESF Exploratory
Workshop, Lecture Notes in Artificial Intelligence, 2477, (Springer:

Cyber-security is concerned handling the problem of malicious use of
computers and networks. I am especially interested in the statistical
problem of anomaly detection in network traffic data.

computer network using multivariate adaptive estimation", IEEE ICDM
Networks Workshop 2013, accepted.
We organised a workshop on network analysis in 2013. This resulted in
a forthcoming edited volume.
I have a long term interest in Credit Scoring, particularly for use in
classification problems. Some recent work:
