Dr. Mark Nunnally is a physician, educator and researcher at the University of Chicago. As a clinician, Dr. Nunnally performs surgical procedure anesthesia in the operating room. He also performs critical care medicine as an attending intensivist in the Surgical, Cardiothoracic and Burn Intensive Care Units (ICUs). During his residency with the Department of Anesthesia and Critical Care at the University of Chicago, he was twice selected as the Resident of the Year and was named Chief Resident in his fourth year. Dr. Nunnally began his research with the Cognitive Technologies Laboratory during his residency. He went on to perform a year-long fellowship in Critical Care Medicine at the University of Pennsylvania. While he was in his third year (CA-3) with the Department of Anesthesia and Critical Care, he presented three abstracts on his work related to complex technology at the 2002 Annual Meeting of the American Society of Anesthesiologists (ASA). He presented yet another abstract at the ASA's 2003 Annual Meeting . 

Dr. Nunnally's research interests concern the role of technology in patient safety.  His work explores a technology fallacy: that technology, instead of consistently improving patient safety, often contributes to failure in novel, unexpected ways.  His work to date has focused on infusion devices, delivery systems and incident reporting.
