Faculty and Staff
JOHN F. ALCORN, PhD
Dr. Alcorn received his PhD in Cell and Molecular Biology from Duke University in 2003. During this time he worked with Dr. Jo Rae Wright on the host defense properties of lung surfactant proteins in the context of bacterial pneumonia. Following his training, he completed a post-doctoral fellowship at the University of Vermont Lung Center with Dr. Yvonne Janssen-Heininger.
Dr. Alcorn's projects were focused on inflammatory signaling in mouse models of asthma and acute lung injury. His expertise includes immunology, cell biology, molecular biology, lung physiology, and disease modeling. His current position is in the Division of Pulmonology, Allergy, and Immunology at Children's Hospital of Pittsburgh, where he is focused on the immunologic mechanisms of severe and steroid insensitive asthma, a significant source of morbidity and mortality in the western world. He is particularly focused on T cell immunity and epithelial cell biology.
NADIA BOUTAOUI, PhD
Dr. Boutaoui obtained her PhD in genetics from the University of Reading (England) and trained as a postdoctoral associate at the Brigham and Women's Hospital (Harvard), where she later became an epigenetics specialist. She joined the Children's Hospital of Pittsburgh as a Laboratory Director in July 2010.
Dr. Boutaoui has extensive experience in genetics/epigenetics and has implemented and managed genome wide genotyping and methylation platforms for multiple studies. She is interested in using genetics and epigenetics tools to understand the effect of nutrition and environmental exposures on respiratory diseases such COPD and asthma. She has established a quality control pipeline for Genome Wide Association Studies (GWAS).Dr. Boutaoui and colleagues have identified FAM13A as a COPD susceptibility locus and showed that variable DNA methylation is associated with COPD and lung function.
JUAN C. CELEDON, MD, DrPH
Dr. Celedón is the Niels K. Jerne Professor of Pediatrics and the Division Chief of Pediatric Pulmonary Medicine, Allergy and Immunology at Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh. Dr. Celedón completed medical school at Pontificia Universidad Javeriana School of Medicine in his native Colombia. He trained in internal medicine at Beth Israel Deaconess Medical Center in New York City and in pulmonary and critical care medicine at Brown University School of Medicine. In 1999, he became a research fellow/instructor at Channing Laboratory. There he developed a research program into the epidemiology of lung disease. Since that time, his research has focused on the effects genetic variants, environmental exposures and behavioral factors have—working independently and together—on the origin and development of lung disease. He is also a Professor of Medicine and Human Genetics at the University of Pittsburgh, and the Director of the Pediatric Environmental Medicine Center of Children's Hospital of Pittsburgh of UPMC.
Dr. Celedón's research goals are to identify genetic and environmental influences on the development of airway diseases in general and in ethnic minorities in particular. He leads research studies of the genetics and epidemiology of asthma in Puerto Rican children, as well as a study of the genetics of chronic obstructive pulmonary disease (COPD) in Costa Rica.

After completing residency, Dr. Gauthier spent a year as a hospitalist with the Pulmonary Stepdown Service at UPMC Presbyterian and as a general hospitalist covering nights in the ICU at UPMC East. During this time he also pursued research focusing on a novel enzymatic pathway for nitrite reduction regulating NO synthesis. After his hospitalist year, Dr. Gauthier began his fellowship in Pulmonary and Critical Care Medicine at UPMC. Since starting fellowship, Dr. Gauthier’s research interests have shifted to severe asthma looking into the glucocorticoid receptor pathway and its role in refractory disease. During his time away from his clinical and research duties, Dr. Gauthier enjoys ballroom dancing, running and learning bass guitar.

ANURADHA RAY, PhD
Dr. Anuradha Ray is a Professor of Medicine and Immunology at UPMC Montefiore. She received her Ph.D. from Calcutta University in India. She underwent postdoctoral training at Cornell University, Ithaca, NY and at Rockefeller University in New York. She was on the faculty at Rockefeller University and at Yale University between the years 1990 and 2001 before moving to the University of Pittsburgh.
The primary goal of Dr. Ray's research is to understand immune mechanisms involving interactions between dendritic cells (DCs), T helper cells and T regulatory cells as they relate to the regulation of chronic inflammatory diseases in the lung and the gut such as asthma and inflammatory bowel disease. She is also interested in mucosal defense mechanisms against infectious agents. All studies in her laboratory employ genetically altered mice and various immunological, molecular, biochemical and imaging techniques. Her research has been continuously funded by multiple grants from the NIH. Currently, she is Principal Investigator on 3 grants, 2 RO1s and a SCCOR grant Project and is also a co-investigator on additional grants. She was invited to be a member of the Faculty of 1000 Biology in the Immunology discipline.
PRABIR RAY, PhD
Dr. Prabir Ray is a Professor of Medicine and Immunology at the University of Pittsburgh School of Medicine. He received his Ph.D. from Calcutta University in India. He received postdoctoral training at Cornell University, Ithaca, NY and at Sloan-Kettering Cancer Institute in New York. He was on the faculty at Yale University between 1990 and 2001 after which he joined the faculty in Pulmonary, Allergy and Critical Care Medicine with a co-appointment in the Department of Immunology at the University of Pittsburgh.
Dr. Ray pioneered the development of inducible cell-specific transgenic mice in the early years of his career and using this system showed an important role for the growth factor KGF in protection from lung epithelial cell death during lung injury. His research in the area of innate immune mechanisms regulating adaptive immunity led to the identification of a central role of the c-kit-PI3 kinase axis in promoting IL-6 but inhibiting IL-12 production in dendritic cells resulting in Th17 and Th2 differentiation and development of the asthma phenotype in an animal model. Ongoing research in Dr. Ray's laboratory encompasses two major areas, which are studies of innate immune mechanisms that mediate resolution of lung inflammation and protect from lung injury after pneumonia and the impact of early life viral infections on immune mechanisms that predispose to asthma in adult life. These studies utilize animal models of disease and human samples which are analyzed using immunological, molecular, biochemical and imaging techniques. Dr. Ray's research has been continuously funded by grants from the American Lung Association and the NIH.
