Profile

Biography

I was originally an Astrophysicist, studying how stars formed. I developed an interest in whether life can be found on planets other than the Earth and so decided to broaden my knowledge by moving into the rapidly expanding field of bioinformatics. I am interested in applying mathematics and statistics towards all areas of scientific research. My research efforts are concentrated on the analysis of data-rich functional genomics experiments. These include microarrays and I collaborate with a number of biologists and medics.
