JULIE LUMENG, MD More
Professor of Pediatrics; Director, Center for Human Growth and Development
Specialty: Child Eating Behavior; Maternal Feeding; Stress Eating

“I am thrilled to have the opportunity to collaborate with individuals in diverse disciplines to address the problem of childhood obesity.  Addressing childhood obesity successfully will require collaborations at the edges of different disciplines and I’m very enthusiastic about learning from my colleagues and expanding my own thinking.”

Julie Lumeng is the Thomas P. Borders Family Research Professor of Child Behavior and Development in the Department of Pediatrics at the U-M Medical School and Director of the Center for Human Growth and Development. She is a developmental and behavioral pediatrician who studies stress, eating behavior, and contributors to obesity risk in young, low-income children. For the last decade, Dr. Lumeng’s work has been primarily within Head Start. She is currently examining how stress in children’s lives may alter stress hormones, which may drive appetite and lead to excessive weight gain; how differences in Head Start program characteristics may be associated with differences in rate of weight gain over the course of the academic year in Head Start; and how maternal feeding practices are associated with childhood obesity among 5-year-old Head Start graduates. She is currently directing a 4-year randomized controlled trial within three different Head Start programs in Michigan, examining how both nutrition and parenting interventions may prevent obesity. Dr. Lumeng completed her MD (1997) and training in Pediatrics at the University of Michigan, and a fellowship in Developmental and Behavioral Pediatrics at Boston University.
