I an a graduate of the University of Virginia and the Case Western Reserve University School of Medicine. I was trained in Pediatrics at Rainbow Babies and Children's Hospital in Cleveland, where I also served as Chief Resident. I completed my Fellowship in Pediatric Critical Care Medicine at the Children's Hospital of Pittsburgh. After my clinical training, I stayed on as faculty at Pittsburgh on an NIH T-32 grant before being recruited back to Cleveland in 2013. I served as Chief of the Division of Pediatric Critical Care Medicine from 2019 until my departure in 2025 . At Rainbow, I also co-directed their PICU Fellowship Program and their PICU Research Program, held the current Linsalata Family Distinguished Chair in Pediatric Critical Care and Emergency Medicine, and was a Professor at the Case Western School of Medicine. I joined Children's National Hospital as the Chief of Critical Care Medicine in December, 2025.

I have published more than 120 peer-reviewed manuscripts and authored numerous book chapters, editorials and invited reviews, most of which focus on acute respiratory failure and critical bronchiolitis. I am the co-founder of BACON (Bronchiolitis: Advancing Care and Outcomes Network), the bronchiolitis research subgroup of PALISI, which is the largest PICU research collaborative in the world. I have served as an invited expert on several national and international projects related to acute respiratory failure and bronchiolitis, including the second Pediatric Acute Lung Injury Consensus Conference and the American Academy of Pediatrics' HIFLO project to reduce unnecessary usage of high-flow nasal cannula. For my service locally and nationally, I was denoted as a University Hospitals Distinguished Physician in 2022, received multiple Society of Critical Care Medicine Presidential Citations, and was elected as a Fellow of the American College of Critical Care Medicine in 2020 and to the Society for Pediatric Research in 2022.
