The Eating & Health Module was fielded 2006-08. Time is a valuable resource, and time use data allows researchers to analyze the choices people make in how they spend their time, along with the time and income constraints they face. She is currently researching Americans' time use on food and eating; physical activity such as walking and cycling; and travel to grocery shopping. Research also includes analysis of low-income individuals' time use patterns and time constraints.
