Our Team

Dr. Amanda Staiano is a faculty member and Director of the Pediatric Obesity & Health Behavior Laboratory at Pennington Biomedical Research Center. She also holds an adjunct appointment in LSU's Department of Psychology. Dr. Staiano earned her PhD in developmental psychology and master of public policy at Georgetown University, followed by a master of science in clinical research at Tulane University. Her primary interest is developing and testing family-based healthy lifestyle interventions that utilize innovative technology to decrease pediatric obesity and its comorbidities. Her research has involved over 1500 children and adolescents, including randomized controlled trials and prospective cohorts, to examine the influence of physical activity and sedentary behavior on body composition and cardiometabolic risk factors.

Due to Dr. Staiano's specific interest in using technology to promote physical activity and healthy behaviors, she was recently PI of the GameSquad study, a randomized controlled trial that tested the efficacy of a 6-month physical activity program for children’s weight management delivered via exergaming, wireless activity monitoring, and telehealth counseling, funded by the American Heart Association (AHA 15GRNT24480070). Her other current trials utilize technology for behavior change, including developing and testing a mobile app for parents of preschoolers to increase children’s physical activity and improve self-regulation skills (NIH R21HD095035) and the use of telehealth counseling in a primary care-based pragmatic trial of children with obesity (PCORI PCS-2017C2-7542 and CDC U18DP006425 Childhood Obesity Research Demonstration/ CORD 3.0).

Her previous studies include two large epidemiological studies of children’s physical activity: an NIMHD-funded study of 175 preschool-aged children in daycare centers (U54MD008602-P02UAB) and a USDA-funded study of 342 adolescents 10 to 16 years of age, including 41% ethnic minority and 50% with overweight or obesity (USDA 3092-51000-056-04A). Dr. Staiano's research studies employ a variety of innovative behavioral tools including exergaming, mobile apps, and telehealth counseling, coupled with study designs that utilize dietary recall, remote data collection and intervention delivery, physical activity assessment via accelerometry and heart rate monitors, observational behavioral analysis of activity, the development and implementation of age-specific exercise protocols, and other behavioral and psychological assessments.

Drawing from her public policy training, Dr. Staiano participates in scientific advocacy at the national, state, and local level.

She earned a Bachelor of Arts degree in psychology from Loyola University New Orleans in 1999 and a Master of Arts degree in psychology from Southeastern Louisiana University in 2001. After completing her Master's degree, she worked at Pennington Biomedical (2002-2004) in the Division of Scientific Education. Following her graduation with a Doctorate in Sociology from LSU and her appointment as Assistant Professor of Sociology at Louisiana Tech University, Dr. Bogen chose to pause her professional employment track and focus on her role as caretaker within the sandwich generation. Demographically speaking, the sandwich generation is the cohort responsible for raising their own children while also caring for their aging parents. That experience has provided a significant framework for her future research endeavors.

As a researcher and educator trained in the social and behavioral sciences, she has a comprehensive set of academic, clinical, and professional experiences, including grant writing, program management, data analysis, survey methodology, questionnaire construction, facilitating engaging presentations and advising undergraduate students. While her primary research interests include social networks, health behaviors, and community engagement, she has worked on various projects, ranging from prosocial responses and evacuation behaviors during natural disasters to weight loss maintenance, to content analyses and memory and cognition recall processes. She is excited to be a part of the Pennington Biomedical team and eager to share her knowledge, skills, and abilities with the Greaux Healthy Initiative.
