Erica D. Walker

Assistant Professor of Epidemiology, Brown University
I am an Assistant Professor of Epidemiology at the Brown University School of Public Health. I have extensive experience with environmental exposure assessments, environmental exposure modeling, community surveying, and community engagement. I also run Community Noise Lab, here. Our lab’s primary aim is to explore the relationship between community noise and health, holistically. We accomplish this by working directly with communities to support their specified noise issue using: real-time monitoring and exposure modeling; our smartphone app, NoiseScore; community noise surveying via our National Environmental Quality Survey; laboratory-based experiments, and community engagement activities.

We are currently working in the Jackson Metropolitan Statistical Area in Jackson, Mississippi, measuring noise pollution but are also measuring both air pollution and water quality.
