Assistant Professor of Epidemiology (Microbial Diseases)

Research Interests

Transmission dynamics; Rotavirus; Typhoid fever

Research Summary

Professor Pitzer uses mathematical models for the transmission dynamics of infectious diseases to understand patterns in the distribution of cases over time and space, and to predict the potential impact of interventions. By integrating epidemiological data analysis with concepts from disease ecology, she studies how characteristics of host-pathogen interactions affect the population-level spread of disease. Current projects include understanding the dynamics of rotavirus and the potential impact of vaccination in developing countries; evaluating strategies for controlling typhoid fever in endemic countries; and understanding how climatic factors influence the seasonality and spatiotemporal spread of RSV.
