I am a member of the Intelligent Systems research
group in the Department of Electronics
at the University of York, UK. My research interests are centred on the study of alternative
representations for evolutionary algorithms and their application to problems
in medicine and image processing. My
theoretical studies concern a specific example of evolutionary computation
known as Cartesian genetic programming (CGP) [1-4], originally developed by Julian Miller and a
novel representation inspired by the human immune system [5]. Medical applications for these algorithms include Parkinson’s
disease [6-10], Alzheimer’s disease [11] and the detection of malignant
microcalcifications in mammograms [12-13].
Recent work has led to the development of a novel non-invasive system
to aid diagnosis of Parkinson’s disease by using commercially available
peripherals such as a digitizing tablet to measure the cardinal symptoms of
tremor and bradykinesia (a slowing of movement). Funding has enabled clinical
trials to be undertaken at Leeds General Infirmary and the Royal Liverpool
University Hospitals, and a patent protecting the technology is currently
being filed. I also enjoy working on the application of rich media
technologies to cultural and heritage museum exhibits. Exploiting digital
video, sound and interaction has led to a number of projects at regional and
national museums, including the Yorkshire and Castle museums in York, the
Royal Museum of Edinburgh and the National Railway Museum, all of which use
video as an interactive media to enhance the learning experience and facilitate
knowledge transfer. Along with Stefano
Cagnoni, I co-founded MedGEC, the GECCO Workshop on medical
applications of genetic and evolutionary computation, which is now in its
sixth year. We are also editors for a forthcoming book on the subject due for
publication in 2010. I was recently tutorial chair for the IEEE Congress on Evolutionary Computation
(CEC2009) in Trondheim and am local organiser for the forthcoming International Conference on Evolvable Systems
(ICES2010) to be held in York, in September 2010. I am associate editor for Genetic Programming
and Evolvable Machines, the Journal of Artificial Evolution
and Applications, and a member of the editorial board for the International
Journal of Computers in Healthcare. 1. Miller, J.F. and Smith,
