Carolyn S. Calfee (born 1973) is a Professor of Medicine and Anaesthesia at the University of California, San Francisco.
She works in intensive care at the UCSF Medical Center where she specialises in acute respiratory distress syndrome.
[7][13] Her research identified that the infection attacks the alveolar epithelium, small air sacs that usually prevent fluid entering the lungs.
[7] In this specific type of RNA virus, a human's immune system response can be so intense that it damages the lungs.
[7] Calfee analyses the fluid and blood samples to understand what factors cause the most extreme responses of coronavirus disease.
At the time, Calfee served as an intensive care physician, and remarked that “the scale and severity of this epidemic is like nothing any of us have experienced,”.
