I have  a strong commitment toward understanding how yeast and human cells engage homologous recombination (HR) as tool in eliminating DNA breaks and crosslinks. As first defined in S. cerevisiae, HR is mediated by genes of the RAD52 epistasis group. The efficiency of HR catalyzed by the RAD51 recombinase is regulated by the tumor suppressors BRCA1, BRCA2, PALB2, and BLM and by components of the Fanconi anemia (FA) pathway of DNA damage response/repair in humans, providing compelling evidence for a key role of HR in cancer avoidance. Our studies have already led to many original findings and provided much-needed conceptual and experimental frameworks for the continual dissection of HR and FA mechanisms. To date, I have published over 200 original research articles.
