Our research seeks to understand biological structure and its relationship to function by employing a combination of experimentation (structural biology/biophysics) and computation (computational biology/bioinformatics) to answer questions that neither computation nor experiment can answer alone.  Questions needing this combined approach include elucidating structural information from challenging systems, where we combine multiple biophysical and biochemical tools to build coherent models.   These questions also include the functional consequences of the interactions between and within molecules that are revealed by structural models.  Here we combine sequence information, the generation and testing of mutant and chimeric proteins, and modeling and analysis to understand the true importance of amino acid interactions.


The biological systems that we employ for our studies are drawn from our longstanding interests in (i) the damage that results to macromolecules upon aging and their repair by cellular processes and (ii) the interactions between organisms as they form symbiotic, mutualistic or parasitic relationships.  In both these areas, macromolecular structure intersects with evolutionary strategies to determine the health, reproduction and longevity of organisms and ecosystems.
