Prof Juliet Pulliam, PhD


Research theme: Rapid Response to Emerging Threats

Prof. Juliet Pulliam is Director of SACEMA and Professor of Applied Mathematics at Stellenbosch University. Prior to moving to SACEMA in July 2016, she spent five years as a faculty member at the University of Florida, where she was also the inaugural director of the International Clinics on Infectious Disease Dynamics and Data (ICI3D) Program from 2012-2016. Juliet received a PhD in Ecology and Evolutionary Biology from Princeton University in 2007, after which she spent a year as a postdoctoral fellow at the Center for Disease Ecology at Emory University and three years as a Research and Policy for Infectious Disease Dynamics (RAPIDD) Program Fellow at the US National Institute of Health's Fogarty International Center. Her research focuses on quantitative approaches to infectious disease epidemiology, particularly zoonotic and vector-borne infections in resource-limited settings.
