My current reseach program focuses on creative ways to mine, visualize and integrate data from structural and functional genomic research. I am particularly interested in the evolution of macromolecular structure and networks in biology, the reconstruction of phylogenetic history, and the incorporation of evolutionary considerations in genomic research. Research relates to the ‘mapping’ of genotype, phenotype, function and fitness to each other, and how this mapping can be used to study origins of molecular diversification, biological systems, processes that are linked to co-evolutionary phenomena (such as pathogenesis and symbiosis), and levels and patterns of genome-wide muation.
Evolution of macromolecular structure and genomic demography: Most functional constraints on the evolutionary divergence of molecules operate at the level of tertiary structure. Consequently, three-dimensional structures are generally more evolutionary conserved than sequences. We have therefore chosen to reconstruct phylogenetic history directly from the structure of proteins and nucleic acids. In these studies, structure, function, and genomic demography are embedded directly into phylogenetic analysis and molecules and genomes compared at a wide range of evolutionary levels, from the subspecies analysis of a fungal plant pathogen to the universal tree of life. This phylogenetic approach can be used to unravel evolutionary processes and uncover functional relationships in RNA molecules, proteomes, and protein architectures. Current studies: (1) compare systematically the structure of proteins and nucleic acids at different evolutionary levels, (2) establish which are the ‘contextual’ constraints imposed by the function and inherent properties of these molecules, and (3) delimit a structural morphospace for phylogenomic analysis.
