Samuel Jenness, PhD
Assistant Professor // Department of Epidemiology

I am an infectious disease epidemiologist specializing in mathematical and computational approaches for studying the drivers of and prevention strategies for infectious disease through the framework of dynamic transmission networks.
As an Assistant Professor in the Department of Epidemiology at the Rollins School of Public Health of Emory University, I lead the EpiModel Research Lab and also collaborate on several projects in both methods and applications for infectious disease epidemiology.
My methodological research focuses on the development of an open-souce software platform for epidemic modeling, EpiModel, which allows users to build, simulate, and analyze complex mechanistic models for transmission of arbitrarily defined infectious disease systems. EpiModel provides a powerful toolkit for modeling dynamic contact networks that are often fundamental for representing transmission of diseases requiring direct contact. EpiModel has been used in over 50 scientific publications, both by my group and modeling researchers around the world!
My applied research focuses on the epidemiology of HIV, sexually transmitted infections, and other infectious diseases. I am interested in how we can use mechanistic modeling and network science frameworks to understand the drivers of these diseases, and to design and evaluate effective prevention strategies. Recent applications have used models to simulate the co-circulation of multiple co-circulating pathogens within the same population, since the risk factors for acquiring one disease may depend on the epidemic dynamics of other infections transmitted along the same contact network.
More broadly, the work of my EpiModel Research Lab involves addressing these questions with research in the following domains:
- Infectious disease epidemiology
- Mechanistic/mathematical modeling of infectious disease
- Network science
- Causal inference methods for epidemiology
- Survey research design and analysis
- Computational epidemiology & scientific software development
