Christian Rosas-Salazar, MD, MPH, is a pediatric pulmonologist and clinical translational investigator at Vanderbilt University. Dr. Rosas-Salazar received his medical degree from the Universidad Autonoma de Guadalajara. He then completed a pediatric residency at Children’s Hospital of Michigan and a pediatric pulmonary fellowship at Children’s Hospital of Pittsburgh of UPMC. He is also a graduate of the Master of Public Health Program of the University of Pittsburgh. His current scientific program focuses on 1) examining genetic, environmental, sociodemographic, and lifestyle factors that shape the early-life respiratory microbiome, 2) evaluating the role of the early-life respiratory microbiome in the programming of the immune response, the severity of acute viral respiratory infections in infancy, and the origins of pediatric asthma phenotypes, and 3) developing novel interventions to manipulate the early-life respiratory microbiome with the ultimate purpose of preventing acute and chronic lung diseases in children. His contributions to research have been recognized by honors from the American Thoracic Society, the American College of Chest Physicians, the Society for Pediatric Research, and the Delta Omega Honorary Society in Public Health, among others. His scientific program is supported by funds from the Parker B. Francis Fellowship and the U.S. National Institutes of Health.

Dr. Ronen Bar-Yoseph is the director of the Pediatric Pulmonology Institute and head of the Children's Physical Activity and Exercise Clinic and Lab at Rambam Health Care Campus. His primary research focus is physical activity and gas exchange kinetics across the life span, development and standardization of exercise protocols and the use of pediatric exercise as medicine. Dr. Ronen Bar-Yoseph seeks to better understand the kinetics of oxygen consumption in healthy children and in children with different clinical conditions. His research project begins the process of systematically identifying the best protocols to use for children and young adults. Through oxygen consumption analysis, he strives to better understand how children’s bodies cope with physiological challenges that arise. This research could lead to improved and more accurate fitness assessment both in health and disease. “The key to understanding why healthy children or children with chronic diseases are limited in their physical activity lies in advanced mathematical modeling of how children use oxygen while exercising.” Dr. Bar-Yoseph has participated in a wide range of clinical and basic research projects and a co-author of the chapter on exercise and physical activity in the "Kendig's Disorders of the Respiratory Tract in Children". His main research interest are physical activity and exercise in health and chronic conditions, particularly in the pediatric population (i.e. - asthma, cystic fibrosis, childhood malignancies, and congenital heart disease) from basic research to the clinic and back, translational science and physical activity as a tool for personalized medicine (Exercise Is Medicine). He is a member of the Israel Society for Clinical Pediatrics, the Israeli Association of Pediatric Pulmonology, the Israel Society of Sports Medicine and the American College of Sport Medicine (ACSM). Dr. Bar-Yoseph is also a consultant for the UC Irvine Cardiopulmonary Center Clinical Exercise Laboratory @ Irvine, California, USA.
