Shannon Gallagher

I am working with Bill Eddy investigating the statistical properties of agent-based models and their relationship to compartment models for applications in epidemiology. More specifically, I am interested in model selection and model validation in these contexts in order to create more accurate and interpretable models in order to better predict and curb the spread of infectious disease.

Other interests include the production and maintenance of synthetic ecosystems (such as SPEW made with Lee Richardson and Sam Ventura), data visualization (such as SPEW View, which won first prize at the MIDAS Mission Public Health Hackathon in 2016), sports analytics (see Kayla Frisoli , Amanda Luby, and my Honorable Mention and $1,000 award paper at CMSAC18), and improving community engagement and support for the statistics community via Women in Statistics (see this recent article that was in the news).

Research Groups

As a part of the MIDAS Informatics Services Group, I am producing tools and analyzing data for infectious disease modeling. Specifically, we have made SPEW, an R package to create agents for use in agent-based models.

I am a member of the CMU Sports Analytics Graduate Student group. Most recently, my collaborators and I won an Honorable Mention for our submission for CMSAC Reproducible Research Competition.

For my first-second year Advanced Data Analysis Project, I predicted the incidence of the flu using an Empirical Bayes model with regional dependencies as a part of CMU DELPHI.

As an undergraduate at CMU, I worked with the NSF Census Research Network on a project about record linkage of multiple databases.
