Tara Cohen, PhD
Tara Cohen, PhD, is a human factors research scientist and assistant professor of surgery at Cedars-Sinai. In 2013, she received her bachelor's degree in psychology from the University of Southern California. While completing her undergraduate work, Cohen also earned her private pilot's license. In 2017, she earned her doctorate in human factors from Embry-Riddle Aeronautical University in Daytona Beach, Florida. Her research interests involve proactive approaches to patient safety through potential threat identification. Cohen has published her work in a number of peer-reviewed journals including Anaesthesia, American Journal for Medical Quality, Journal for Patient Safety, Journal for Medical Systems and the Journal for Healthcare Quality. She has also given a number of presentations at both national and international meetings.
Cohen's interest in human factors is drawn from her background in psychology, passion for aviation and interest in design. Throughout her private pilot training, she became interested in the complexity of systems, how they function and how to better design them for the user. More specifically, she has an interest in understanding how human behavior plays a role in complex environments and what can be done to increase safety and efficiency throughout various systems. Moreover, her most recent research involves investigating the role of intraoperative flow disruptions or events that serve to deviate team members from their current task (e.g., nonessential personnel, poor technology/tool design, layout issues, inefficient planning, etc.) during surgical procedures.
