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 such as vaccination. 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.

Activities

  • Rotavirus vaccine impact in developing countries Bangladesh; Ghana; Malawi (2015 - 2019)

    We are using a combination of statistical and mathematical modeling to predict the impact of rotavirus vaccination in developing countries, then validating our predictions against the observed impact of vaccination in Malawi and Ghana.

  • Rotavirus vaccine impact in Belgium Belgium (2013)

    In collaboration with researchers in Belgium, we are using mathematical models to understand the impact of vaccination on the incidence and distribution of genotypes causing rotavirus gastroenteritis.

  • Typhoid fever dynamics and potential impact of vaccination India; Malawi; Nepal; Vietnam (2012)

    We are using mathematical models to better understand epidemiological patterns in the incidence of typhoid fever, predict the potential impact of vaccination, and identify key questions for future field and laboratory studies.
