Dr. Erica Walker is an assistant professor of epidemiology and director of the Community Noise Lab at Brown University in Providence, Rhode Island. She has extensive experience with environmental exposure assessments, environmental exposure modeling, community surveying, and community engagement. She runs Community Noise Lab, whose primary aim is to explore the relationship between community noise and health, holistically. This is accomplished 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 the National Environmental Quality Survey; laboratory-based experiments, and community engagement activities.
