Justin Lessler, PhD
Department of Epidemiology, Bloomberg School of Public Health
The Johns Hopkins University
Justin Lessler is an associate professor in the department of epidemiology researching the dynamics and control of infectious disease. His work includes development and application of novel methods to understand the geographic spread of HIV and other infectious diseases, field studies to understand disease transmission, and implementation of dynamic models to inform health policy.
Methods of expertise
Computational modeling, biostatistics, spatial analyses
Services available to CFAR investigators
HIV mapping, estimation of disease risk, strategic and inferential modeling
- HIV Incidence, Transmission Dynamics and Combination HIV Prevention: Rakai Uganda
The goal of the proposed research is to assess whether targeted CHP in hotspots is likely to reduce transmission in the larger general populations. The findings will inform strategies for HIV prevention in rural SSA.
- Influenza Immunity and Survival in Aging Populations
Recent studies suggest that the oldest individuals, with a lifetime of influenza exposure behind them, have elevated antibody titers to influenza across strains. This study aims to understand how and why this increase in antibody titers occurs, and what role survival effects, patterns of infection and the biology of the immune response play in creating patterns of immunity over a lifetime of influenza exposure.
- Continued and Expanded Cholera Modeling Efforts
This project aims to use mathematical and computational modeling to provide essential guidance for the optimal use of oral cholera vaccines (OCV) as the vaccine supply expands, including important information on when the vaccine can be used to the greatest effect, who should be targeted when the vaccine is used, and the potential public
