Research Summary

The Bharti lab investigates the underlying links between humans, pathogens, and the environment. We work to identify the mechanisms that give rise to heterogeneities in host disease burden and risk across scales, across spatial and temporal scales. We study the dynamics of host-environment interactions that drive movement and contact patterns as they relate to to pathogen transmission and access to health care.

Behavior limits COVID-19 spread between University and community

When universities across the U.S. opted to return students to campus for in-person learning during the coronavirus pandemic in the fall of 2020, surrounding communities were understandably concerned that COVID-19 infections rates would significantly increase. In response, several Penn State researchers formed the Centre County COVID-19 Data 4 Action Project (D4A) to conduct anonymous surveys and biological testing for nonstudent residents and Penn State students to document the social and economic impacts of the pandemic in one community.
