My group at McMaster University is interested in the area of molecular evolution, bioinformatics, and sequence analysis. Our research attempts to understand how the processes of evolution act to cause the changes observed between molecules, between genes and between genomes. The recent advances in molecular genetics are providing a storm of new data on DNA sequences, on gene structure and higher order genomic structure. However, the implications of these new data are not always clear. This area of scientific inquiry is inter-disciplinary between biology, computer science and mathematics. We make use of computer based analysis, statistical analysis and mathematical models to answer broad questions about the molecular biology of all organisms.
