At the Computational Biochemistry Research Group we are interested in the modelling and analysis of biological problems at the molecular level. Our expertise lies in particular in searching algorithms, optimization algorithms, mathematical modelling, and computational systems. Most of our research efforts are concentrated on the Orthologous MAtrix (OMA) project. This particular project aims to produce, automatically, reliable orthologous groups of proteins that are derived from entire genomes. We offer the results and general services through the internet and through the distribution of the Darwin system for bioinformatics computations.
