My research in yeast focuses on the fundamental question: What factors make a given molecule a “good substrate” for homologous recombination?  Such factors determine how often non-allelic repetitive DNA recombines to produce chromosomal aberrations associated with cancer and hereditary diseases.  To address this question, I am developing genome-wide tools to determine what factors are most important in governing recombination between naturally occurring repeats.  In addition to spontaneous recombination events, recombination machinery can also be harnessed as a powerful tool to precisely modify genomes.  I am using genetic screens to identify rate-limiting steps during genome modification.
