Catherine L. Chen is a board-certified anesthesiologist and health services researcher with a primary research interest in optimizing the quality and value of care that patients receive during the perioperative period. She holds an appointment as an associate professor in the UCSF Department of Anesthesia & Perioperative Care and at the Philip R. Lee Institute for Health Policy Studies. Her research program is focused on identifying and reducing low-value care, especially instances of perioperative health care overutilization that may not be beneficial and can potentially harm surgical patients.
