Jennifer Butcher, Ph.D. (

Dr. Butcher's research interests include family functioning in pediatric chronic illness, adherence to medical regimens, developmental transition of responsibility over medical regimen tasks, cystic fibrosis, and sickle cell disease.




Dawn Dore-Stites, Ph.D. (

Dr.Dore-Stites primary research interest is sleep problems within a chronically ill population. Secondary research interests include factors related to adherence and the transition of adolescents with chronic illness to adulthood.





Barbara T. Felt, M.D. (

Dr. Felt is a subspecialty board certified, developmental-behavioral pediatrician whose research focuses on characterizing the behavioral effects of early iron deficiency anemia during early brain development using the rodent model, and exploring the immediate and long-term effects of early iron deficiency anemia during infancy with a focus on prolactin and cortisol response to stress. In collaboration with other faculty, research efforts also include exploring the influence of early experience sleep disruption and/of injury on brain, neuroendocrine, behavioral outcomes (rodent and human), sleep disorders and agression in young children, and the influence of culture on behavior, motor and neuroendocrine outcomes using a dynamic systems approach.

Emily M. Fredericks, Ph.D. (

Dr. Fredericks is a pediatric psychologist whose research focuses on improving health outcomes among pediatric transplant recipients. Currently, Dr. Fredericks has research funding from the Division of Child Behavioral Health to investigate the relationships between health-related quality of life (HRQOL), family functioning and regimen adherence among pediatric liver transplant recipients with the goal of developing a comprehensive assessment strategy to objectively define adherence, and to identify patients and families at risk for poor adherence. Dr. Fredericks is also interested in examining the transition from pediatric to adult-oriented transplant care with the goal of improving long-term health outcomes for pediatric transplant recipients. The ultimate aim of her research program is to develop empirically-supported randomized controlled studies of the efficacy of clinical interventions to improve post-transplant management of pediatric transplant recipients.

Dr. Fredericks also has secondary research interests in the area of pediatric sleep disorders and type 1 diabetes mellitus (T1DM). She is interested in investigating sleep disturbances in children with chronic illness, particularly chronic liver disease, and is involved in projects investigating HRQOL and regimen adherence among children and families with T1DM.


Betsy Lozoff, M.D., M.S. (

Dr. Lozoff is a developmental-behavioral pediatrician whose research focuses on the effects of iron deficiency anemia on infant behavior and development. Iron deficiency is the most common single nutrient disorder in the world. Dr. Lozoff heads a multiuniversity cross-species program project grant on brain and behavior in early iron deficiency. She also directs a large project on iron deficiency in Chile, continues follow-up studies of Costa Rican children who had iron deficiency in infancy, and is part of another large study of micronutrient supplementation in India. The results of research by Dr. Lozoff and others indicate that there are long-lasting developmental disadvantages among children who had iron deficiency as infants.

Julie C. Lumeng, M.D. (

Dr. Lumeng is a board certified, developmental-behavioral pediatrician who studies how social influences on eating behavior and children’s cognitions around food may alter dietary composition and overweight risk, particularly in preschool-aged children and younger. Peers are well-documented to influence choice of food in social settings, but how these influences operate in children of diverse ethnicity and socioeconomic status is less well-understood. She researches children’s eating behavior in Head Start settings, both through the direct observation of behavior during a natural meal and through the presentation of unique behavioral tasks to children that test their cognitions around food. Dr. Lumeng also examines the influences on young children’s overweight risk through the analysis of large data sets, with a particular focus on child care experience and quality, and neighborhood characteristics. Other projects include the evaluation of mother-child interactions around eating, and how maternal behavior affects a child’s eating behavior, both in preschoolers and infants.

Bethany J. Gaffka, Ph.D. (

Dr. Gaffka is a pediatric psychologist whose research focuses on improving treatment outcomes for obese youth enrolled in family-based behavioral weight management programs. Specifically, Dr. Gaffka's research agenda is aimed at 1. Determining parental factors that may contribute to significant child weight loss, and 2. Developing innovative theory-based interventions to ultimately improve treatment outcomes. Currently, Dr. Gaffka has research funding from the Division of Child Behavioral Health to investigate the mechanisms through which parents influence child weight status during participation in a structured family-based weight management program. As a co-investigator, Dr. Gaffka has research funding from the Michigan Institute for Clinical & Health Research, for a Community-University Research Partnership Grant, to examine the feasibility and acceptability of implementing a family-based weight management program for 7 to 11 year old children at the Ann Arbor YMCA. Dr. Gaffka's other research projects include examining psychosocial predictors of attrition and weight loss in pediatric weight management programs.


David E. Sandberg, Ph.D. (

Dr. Sandberg's research activities are closely linked to his clinical service to children with a variety of endocrine-based disorders, and their families. Research activities include the study of psychosocial aspects of short stature and the psychosocial care of individuals born with disorders of sex development (DSD) and families. He recently served as co-investigator of an (NICHD-sponsored) interdisciplinary research network concerned with biological and socialization factors in sexual differentiation; is developing a psychoeducational treatment manual for clinicians caring for newborns with congenital adrenal hyperplasia identified by newborn screen; and designing health-related quality of life measures for individuals with DSD and their families.
