Mary Bushman is a postdoctoral research fellow working with Bill Hanage in the Department of Epidemiology at the Harvard T.H. Chan School of Public Health. They earned their B.A. in Mathematics from Carleton College, followed by their Ph.D. in Population Biology, Ecology & Evolution from Emory University. Their dissertation research, which was partly carried out at the Centers for Disease Control and Prevention in Atlanta, focused on the role of within-host dynamics in the emergence and spread of drug resistance in malaria. Prior to joining CCDD, they worked as a postdoctoral fellow with Rustom Antia at Emory University; their work during this period focused on emergence of novel infectious diseases and antigenic evolution of influenza virus. Their research interests center on the ways in which within-host dynamics and epidemiological dynamics interact, and how such interactions shape the evolution and diversity of human pathogens.
