Appointments and Referrals: 1-800-TRY-CHOP (1-800-879-2467)
Dr. Chiotos is a graduate of the College of William and Mary and the George Washington University School of Medicine, and recently earned a Master’s of Science in Clinical Epidemiology from the University of Pennsylvania. She completed pediatrics residency training at Children’s Hospital of Philadelphia (CHOP), followed by a combined fellowship in pediatric infectious diseases and pediatric critical care medicine.
Dr. Chiotos joined the faculty at the University of Pennsylvania in 2017 and is currently an Assistant Professor of Anesthesia, Critical Care, and Pediatrics with a secondary appointment in pediatric infectious diseases.
Dr. Chiotos’ research focuses on the epidemiology of antibiotic resistant organisms in the pediatric intensive care unit setting as well as antibiotic stewardship in this population. She is involved with several quality improvement initiatives surrounding optimizing antibiotic use and diagnostic evaluation for patients with suspected sepsis at CHOP.
