Dr. Baldassano’s research focuses on children who have inflammatory bowel diseases, and he oversees a large team of researchers at CHOP working to translate discoveries in the laboratory into direct patient care for children. One promising area of current research involves investigating the intestinal microbiomes of children with inflammatory bowel diseases.
Dr. Silverman studies the fundamental aspects of early-life commensal microbes that influence immune system development and function. He discovered that the MHC-II E molecule prevents type 1 diabetes by shaping the intestinal microbiota early in life.
Dr. Tasian and his research team use an epidemiologic framework, including randomized trials and multi-institutional observational studies, to examine the etiology of kidney stone disease and the comparative effectiveness of surgical interventions. He also employs machine learning of complex data to improve diagnosis, risk stratification, and prediction of treatment response for children and adults with benign urologic disease.
Dr. Kelsen’sresearch focus is on the genetic, immunologic, and microbiomic causes of very early onset inflammatory bowel disease. Through a multidisciplinary team approach, Dr. Kelsen and her colleagues perform genetic sequencing to identify causative genetic variants in children with VEO-IBD, study the function of these variants, and use this information to improve the clinical outcomes for these children.
Dr. Zemel's overall research program aims to improve the understanding of lifelong health and how it relates to childhood antecedents of physical growth and maturation, body composition, population ancestry/genetics, and lifestyle factors. Such insight has practical implications for disease prevention and lifelong wellness, as well as broader scientific implications for understanding human plasticity and evolution.
Dr. Weiss' research focuses on epidemiology of pediatric sepsis and mitochondrial dysfunction in sepsis-associated organ injury. The driving hypothesis for his research is that alterations in mitochondrial bioenergetics contribute to organ injury and immune dysregulation in a subset of children with sepsis.
Dr. Hill seeks to understand how the immune system contributes to the two most common chronic diseases of childhood: allergy and obesity. He uses clinical and epidemiological information to guide basic and translational research on the genetic, epigenetic, and immunologic basis of these important conditions.
Dr. Zackular's research is focused on understanding how interactions between the host, gut microbiota, and pathogenic microbes impact human health and disease. His recent efforts center on understanding how the important nosocomial pathogen, Clostridium difficile, interacts with resident gut microbiota during infection and how interspecies cross-talk impacts growth, behavior, and virulence of this pathogen.
Dr. Fisher's research focuses on infections in children with immunocompromising conditions. He is particularly interested in infections in children with cancer and serves as the chair of the Infectious Disease Domain within the Children’s Oncology Group.
Dr. Jacobs’s current research focuses on several areas, including the biochemical, microbiological, and genetic cause of scarring or stenosis of the laryngotracheal airway, and the development of tissue-engineered cartilage and other novel biomaterials for laryngotracheal reconstruction. Dr. Jacobs is also investigating the mitigation of button battery injuries in infants and children
