Reconstructing events in the history of life has a long tradition in the geological and paleontological sciences. However, only with the recent advent of extensive genomic sequencing has molecular biology been able to look backward in time in the same way, using the record of events preserved within the genomes of existing organisms. My research attempts to integrate these methods in order to investigate important questions in evolution: reconstructing ancestral protein sequences and determining the functional roles of proteins existing in organisms early in the history of life.
