Dr. Grimberg investigates the growth hormone (GH)/insulin-like growth factor (IGF)-I axis and clinical issues related to child growth. Her recent research is focused on disparities in, and the decision-making related to, the medical management of children with short stature. She is fascinated by how differential societal pressures for tallness and the advent of an expensive therapeutic have transformed a fundamental aspect of pediatric healthcare.
Dr. Mostoufi-Moab's clinical and research program is focused on endocrine late effects after childhood cancer therapy. She has unique dual training in pediatric endocrinology and oncology with a master's degree in clinical epidemiology. The goal of her research program is to pursue a mechanistic understanding of metabolic and endocrine disorders that occur due to cancer therapy.
Dr. Levine has an active laboratory research program that complements and extends his clinical studies. He has identified the molecular basis of several inherited disorders of mineral metabolism. His research interests extend to the molecular basis for embryological development of the parathyroid glands.
Mary Ellen Vajravelu, MD, MSHP, is a pediatric endocrinologist in the Division of Endocrinology and Diabetes at Children’s Hospital of Philadelphia. She treats all pediatric endocrine conditions, but she has special expertise in prediabetes and type 2 diabetes in children and adolescents.
Dr. Stanley’s lab has identified many of the genes and syndromes associated with congenital hyperinsulinism including ABCC8, GCK, GLUD1, and Turner and Beckwith syndromes. Working with clinical and rodent model studies, his lab team has identified distinctive phenotypes of these disorders, including diazoxide unresponsiveness, leucine sensitivity, and protein sensitivity. Dr. Stanley continues to seek new diagnostic and treatment paradigms for infants with acquired and genetic disorders of hyperinsulinism.
Dr. Ackermann studies diabetes (types 1 and 2) and congenital hyperinsulinism using mouse models, cell lines, and primary human tissue. She aims to identify novel pathways regulating beta cell insulin secretion, leading to innovative therapeutic strategies for these disorders. Current studies include in vivo mouse physiology, ex vivo human islet physiology, CRISPR-Cas9 gene editing, epigenetic modification, and single-cell functional genomics.
Dr. Kolon is an expert in the care of children with genital disorders and renal/bladder/prostate cancers. His expertise in pediatric urologic oncology includes optimizing organ-sparing surgery and preservation of fertility in oncology patients.
Dr. Roizen's research program aims to understand non-calciometabolic effects of vitamin D and to use this understanding to design new therapeutic approaches to common diseases such as sarcopenia and obesity.
Dr. Xanthopoulos's research focuses on the development, implementation, and adherence to medical and lifestyle interventions, including non-invasive ventilation (CPAP/BPAP), eating habits, physical activity, and sleep. She has a particular interest in the interactions among behavioral, lifestyle, psychosocial and physiologic factors as they relate to health and neurobehavioral functioning and quality of life in youth and families.
Dr. Bauer's academic and clinical career are focused on improving the care of children and adolescents with thyroid disease. He has extensive experience and knowledge of thyroid pathophysiology and tumorigenesis, and has been critical to the clinical success of the Children's Hospital of Philadelphia Thyroid Center.
