Christian Testa

I am a statistical data analyst at the Harvard T.H. Chan School of Public Health working with the Public Health Disparities Geocoding Project. I received my Bachelors of Science in Mathematics from Tufts University in 2017.

Research Interests

My research interests focus on mathematical modeling techniques and their public health applications.

Topics I have been particularly interested in recently include:

  • Causal inference
  • Bayesian methods
  • Spatiotemporal statistics
  • Infectious disease epidemiology
  • Flexible, machine learning methods

My recent ongoing work has focused on applying these techniques to understand disparities in COVID-19 outcomes, how discrimination throughout the lifecourse is manifested through changes in epigenetic markers as it relates to epigenetic aging, and how experiences of multifactorial types of discrimination impact people’s health.

My previous work with the Prevention Policy Modeling Lab focused on using dynamic models of infectious diseases to estimate optimal intervention strategies.

The Public Health Disparities Geocoding Project 2.0 was a workshop where my colleagues and I trained 150 Public Health professionals from diverse backgrounds (city and state health departments, advocacy organizations, policy think-tanks, academia, non-profits, etc.) on how to use geo-referenced data for analyses that promote health equity.
