Graham C. Walker
Graham Charles Walker (born 1948) is an American biologist, notable for his work explicating the structure and function of proteins involved in DNA repair and mutagenesis, with applications for cancer, and for understanding rhizobium (bacterial) functions that infect plants and mammals. In addition to his scientific achievements, Walker is coordinating a program at MIT to develop curricular materials in biology. Biography Walker earned a B.Sc. degree from Carleton University, and his Ph.D. in 1974 from the University of Illinois. He did postdoctoral work at the University of Illinois and at University of California, Berkeley with Bruce Ames. He is currently a professor at MIT. Notable publications Errol C.
