Andrew Johnson is a PhD candidate in the biology department at the University of Pennsylvania. He is deeply interested in the scientific and policy challenges associated with modern biodefense, including questions of how to retain public support for pandemic mitigation policies, and how to leverage ecological theory to forecast and manage pandemics. Johnson’s dissertation work is focused on applying classical ecological theory to unorthodox ecosystems, namely the gut microbiome. Prior to his current work, he studied the urban disease dynamics of rabies in Arequipa, Peru.
