Dr. Katherine Berg is a Pulmonary and Critical Care physician at BIDMC and Assistant Professor of Medicine at Harvard Medical School. She is a graduate of the University of Massachusetts Medical School, and completed her Internal Medicine residency at Tufts Medical Center. She completed her fellowship in Pulmonary and Critical Care Medicine at the Harvard Combined Program. Dr. Berg’s clinical investigations focus on understanding how oxygen metabolism changes in the shock seen in severe sepsis and after cardiac arrest, and investigating the utility of metabolic resuscitation. She is currently Principal Investigator of the randomized trial of thiamine to improve oxygen consumption after in-hospital cardiac arrest (THICA) and a co-investigator of the trial of thiamine as a metabolic resuscitator after out-of-hospital cardiac arrest (THACA) trial, as well as multiple other CRS studies. She has recently expanded her clinical and research interests to interventions to maximize long-term recovery after cardiac arrest and other critical illness. She is part of the core faculty of the Critical Illness Survivorship Program, where she sees patients weekly. Dr. Berg is the Chair of the Advanced Life Support Task Force at the International Liaison Committee on Resuscitation, and Chair of the writing group for the 2025 American Heart Association Post-cardiac Arrest Care Guidelines.
