My ON-LINE List of Publications
Teaching
I am currently teaching Data Mining and Knowledge Discovery (a master-level module) and Natural Computation (evolutionary algorithms and swarm intelligence).
Research Interests
I belong to the following research groups:
I am also a member of the
Centre for BioMedical Informatics
My main research interests involve the following areas:
Data Mining and Knowledge Discovery;
Bio-inspired algorithms (mainly Evolutionary Algorithms and Ant Colony Optimisation);
Bioinformatics and the Biology of Ageing;
I got my PhD in Computer Science from the University of Essex, UK, in 1997, doing research on data mining, and I have continued to do research on data mining up to the present. In terms of data mining applications, since 2005 my research has been focusing on creating new data mining methods for bioinformatics (in particular the prediction of protein functions).

Current Research Project - Refactoring and Neutrality in Genetic Programming
This is a 3-year EPSRC-funded project being carried out at the School of Computing, University of Kent. The principal investigator for this project is Dr. Colin Johnson, and the project involves one post-doc research associate. Broadly speaking, the goal of the project is to extend genetic programming methods with concepts and principles from refactoring techniques in software engineering and the theory of neutrality in natural evolution. The project started in February 2010.
Past Research Project - A Synergistic Integration of Natural and Artificial Immunology for the Prediction of Hierarchical Protein Functions
This was an EPSRC-funded multi-institutional project involving 3 institutions: the University of Kent, the University of York and the Edward Jenner Institute for Vaccine Research. The project involved 3 post-doc Research Associates, one post-doc at each institution. This project started in February 2006 and finished in November 2008.
For more information about this project, see the project's website.

Past Research Project - Bio-inspired Classification and Data Mining Algorithms for Bioinformatics
This was an European Union Interreg III project involving 2 institutions: the University of Kent in the UK and the University of Littoral in France. The project involved 1 post-doc Research Associate at Littoral and 1 PhD student at Kent.
The project started in September 2006 and finished in August 2008.
For more information about this project, see the project's website.
Past Research Project - eXtended Particle Swarms (XPS)
This was a large EPSRC-sponsored research project, which came out from the below-mentioned research cluster in Swarm Intelligence. The project involved 5 universities (Essex, Kent, Leeds, Goldsmith and UMIST), industrial collaboration with BTExact and several international collaborators who are key figures in the field. In total (in all the 5 universities) the project involved 5 post-docs full time for two years and 4 PhD students full time for three years. At Kent the project involved one post-doc research associate and one PhD student, and the co-investigator at Kent was Colin Johnson. This project started in October 2004 and finished in September 2007.
Main publication related to this project:
N. Holden and A.A. Freitas. Hierarchical classification of protein function with ensembles of rules and particle swarm optimisation. Soft Computing journal, Vol. 13, No. 3, Feb. 2009, pp. 259-272. (pre-print version)

Past Research Project - Research Cluster in Swarm Intelligence
I have coordinated (jointly with Colin Johnson) an EPSRC-sponsored research cluster in Swarm Intelligence in the UK, in 2003. This was a multi-institutional and interdisciplinary research cluster, involving more than 15 institutions and a good mix of computer scientists, biologists and mathematicians.
