Current OSU Appointments

Associate Professor, Pulm,Allergy,Crit Care & Sleep

Physician, FGP-Pulm-Allrgy-CritCare-Sleep



In addition to running the Sarcoidosis Clinic at OSU, Dr. Crouser is the Section Chief for the Division of Pulmonary and Critical Care Medicine and Medical Director of the ICU at University Hospital East (an affiliate of The Ohio State University Medical Center in Columbus, OH). Under his leadership the ICU structure has been optimized to deliver outstanding care (below target length-of-stay; risk adjusted mortality consistently <0.5) while providing expanded services (e.g., new stroke and acute myocardial infarction initiatives, increasing census). He also serves as an Editor for Critical Care Medicine, the top-ranked journal specializing in critical care, and reviews or serves on editorial boards for more than 20 other journals. He has served on NIH study sections, including an ongoing temporary appointment to the Surgery Anesthesia and Trauma study section (for 3 consecutive cycles), and has also reviewed grants for the Society of Critical Care Medicine, Wellcome Trust (London) and other extramural funding agencies. Dr. Crouser is actively funded by extramural sources for over 15 years, including ongoing support from the NIH to investigate inflammatory diseases that involve the lungs and other organs in the context of acute and chronic illness. His laboratory is among the first to have identified mitochondria as critical mediators of cell and organ dysfunction in the setting of acute systemic inflammatory diseases, including sepsis. His genomic studies in the field of pulmonary sarcoidosis identified novel disease mechanisms and "biomarkers" of disease progression. Ongoing studies in these areas of research promise to provide targets for new treatments for these poorly understood diseases.
