EMGS Special Symposium

Genome Maintenance Systems in Cancer Etiology and Therapy: A Tribute to Paul Modrich

September 18-19, 2019

Co-Chairs: Guo-Min Li, Robert W. Sobol, Joann Sweasy, and Karen Vasquez
Organizing Committee: Farid Kadyrov, Bill Jack, Robert Lahue, Guo-Min Li, A-Lien Lu-Chang, Robert W. Sobol, Michael Su, Joann Sweasy, Karen Vasquez, Leroy Worth

The goal of this EMGS Special Symposium is to celebrate Dr. Paul Modrich’s career-long scientific contributions as a leader of the DNA repair field. The focus of the Symposium is to bring together scientists working at the cutting edge of current efforts to elucidate the molecular mechanisms of genome-maintenance systems and their roles in cancer etiology and therapy that were pioneered by Dr. Modrich. A key outcome of the Symposium will be to stimulate discussions and to further cross-fertilize ideas at the forefront of the field. In addition to invited talks and interactive poster sessions, the program will also include short talks and “poster flash” platform presentations, as a key mechanism to ensure ample attention to the contributions and participation of students, postdoctoral fellows and other early career scientists, and to seek out and actively encourage their attendance at the symposium. We invite scientists in the field to join the exciting symposium.
