I am involved in research in bioinformatics, classification and data mining. I am the leader of the classification and data mining research group in the Statistics section. My full publication info is here

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

Statistical analysis for cell biology
Streaming data methodology
Classification and data mining

Statistical analysis for cell biology

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 with Paul Freemont and Dave Stephens.

Streaming data methodology

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

Anagnostopoulos, C., Adams, N.M. and Hand, D.J. 'Deciding what to observe next: adaptive variable selection for regression in multivariate data streams' in 'Proceedings of the ACM Symposium on Applied Computing (SAC)', 2008, 961-965.

This work is partially supported by the ALADDIN project.

Classification and data mining

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 from the EPSRC ThinkCrime project include

Hand, D.J., Whitrow, C, Adams, N.M., Juszczak, P. and Weston, D.J., 'Performance criteria for plastic card fraud detection tools' J. Oper. Res. Soc., 58, (2008), 956-962.

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

Other activities.

Royal Statistical Society

I am a chartered statistician , since 2009.

I am a member of the committee of the Statistical Computing section of the Royal Statistical Society, having been chair 2005-2008. In addition, I am a member of the "recordings" and "data and society" working groups.

Intelligent Data Analysis

I have been a member of the program committee for the last 4 conferences, and was involved in the organisation of the 2001 conference:

Hoffman, F., Hand, D.J., Adams, N.M., Fisher, D. and Guimaraes, G. (eds.), 'Advances in Intelligent Data Analysis' Proceedings of the 4th International Conference, IDA 2001, Lecture Notes in Computer Science, 2189, (Springer: Berlin) 2001.

and was I was co-chair of the program committee for IDA 2009, held in Lyon, August 2009. Proceedings:

Adams, N.M., Robardet, C., Siebes, A. and J.-F. Boulicault (eds), 'Advances in Intelligent Analysis VIII', Proceedings of the 8th International Symposium on Intelligent Data Analysis, IDA 2009, Lecture Notes in Computer Science, 5772, (Springer: Berlin) 2009

Breaking news!In an exciting development, an extra IDA conference is being planned for May 2010, in Arizona, USA. The website is now available.
