The Gordon Research Seminar on Mammalian DNA Repair is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas. The focus of this meeting is on bringing young investigators (graduate students and post-docs) together to discuss their recent findings in the field of DNA repair in the eukaryotic system. In this meeting we will emphasize various topics in DNA repair including DNA damage signaling, recombination and genomic stability, DNA repair in the context of chromatin, regulation of proteins involved in DNA repair, and the mechanism of DNA repair.
