Erica decided to take one for the team, sold off all of her furniture making and book-binding equipment, moved out of her apartment, and enrolled full-time into the environmental economics and urban planning program at Tufts University. During her time at Tufts, Erica built a traffic noise prediction model and used these predictions to understand the relationship between traffic noise and cardiovascular health in a community right next to a very busy freeway. It was during this time that her advisor (the GREAT Mary Davis) suggested that she should consider this field called public health.
