Research interest

Every time cells divide, the preservation, duplication and transmission of their genetic information must be accurately accomplished. In our lab, we study how cells coordinate the repair of DNA damage with major molecular events like DNA replication and chromosome segregation. With a particular focus on homologous recombination, we currently employ a multi-pronged approach that includes biochemistry, yeast genetics and cell biology to focus on the following questions: i) how the biochemical properties of Holliday junction resolvases can bias repair outcome (crossovers vs non-crossovers); ii) how post-translational modifications regulate the biological functions of DNA repair enzymes and iii) how the misregulation of DNA repair activities may interfere with other cellular processes.
