Guohua Li, MD, DrPH
M. Finster Professor of Anesthesiology and Epidemiology

Dr. Li’s expertise is in the areas of injury epidemiology and clinical epidemiology. His research encompasses innovative research methodology, development of surveillance data systems, and application of novel designs and analytical techniques in studies of the causes and prevention of injuries and adverse outcomes in perioperative care, critical care, and emergency care.  He is the founding Director of the Center for Injury Epidemiology and Prevention and the Center for Health Policy and Outcomes Research in Anesthesia and Critical Care, and the founding Editor-in-Chief of Injury Epidemiology.  He teaches two accredited courses at the Mailman School of Public Health, Injury Epidemiology (P8448) and Clinical Epidemiology (P8450). Dr. Li is a recipient of the Kenneth Rothman Prize (1999), the Guggenheim Fellowship (2005), the John Paul Stapp Award (2009) from the Aerospace Medical Association, and the Excellence in Science Award (2015) from the American Public Health Association’s Injury Control and Emergency Health Service Section.

Dr. Li joined the Department of Anesthesiology at Columbia University in July 2007. As the M. Finster Chair, he is charged with building a center of excellence in health policy and outcomes in anesthesiology and critical care, mentoring junior faculty and clinical research fellows at the Department of Anesthesiology, and playing an active role in research and education programs at the Department of Epidemiology. The center of excellence in health policy and outcomes focuses on several substantive areas relevant to the safety, effectiveness, and efficiency of perioperative care and critical care, including the development of practical tools for measuring risks and clinical outcomes, identification of and intervention on risk factors for adverse outcomes, and examination of the health effects of volatile anesthetics in vulnerable population groups (e.g., children, elderly, and patients with specific comorbidities).    

 

Hannah Wunsch, MD MSc
Instructor in Anesthesiology and Critical Care Medicine

Dr. Wunsch’s conducts research on the epidemiologic of critical illness. She uses large databases to answer questions relating to the organization and delivery of critical care. Her current research interests include examination of the long-term outcomes from critical illness, international comparisons of critical care, and pharmaco-epidemiology in critical care. She currently holds a FAER grant to look at three year outcomes after critical illness in Medicare patients, specifically examining mortality and health care resource use in a large cohort. Another area of work tries to understand how clinicians use sedation in the ICU by examining sedation patterns and the characteristics of patients associated with administration of different sedatives, including dexmedetomidine.

Her research on international comparisons focuses on the question of how rationing decisions are made when resources are limited, and what effect this has on patient care. She investigates patients in the United States and England, characterizing differences in admission practices and patients. Detailed analyses include examination of specific diseases and surgical procedures, with an emphasis on looking at the use of intensive care after major surgery.

Dr. Wunsch completed both her residency in Anesthesiology and Fellowship in Critical Care at Columbia, where she was one of the first three Virgina Apgar Fellows. She also has a Master’s degree in Epidemiology from the London School of Hygiene & Tropical Medicine. She collaborates extensively with researchers at the University of Pittsburgh, the University of Toronto in Canada, and the Intensive Care National Audit & Research Centre in London.
