Cheryl MacKenzie is currently an Engineering Program Project Team Lead for Environment, Safety, and Health (ES&H) Performance Assurance at Sandia National Laboratories, a federally funded research and development center that performs high-hazard work in the areas of energy (solar, wind, other), global security, nuclear weapons, and national defense systems. Prior to her time at Sandia, MacKenzie spent over fourteen years as an Investigator, Human Factors Specialist, and
Investigation Team Lead for the US Chemical Safety and Hazard Investigation Board (CSB), participating in over two dozen in-depth investigations of catastrophic chemical incidents in order to derive lessons to improve safety, human performance reliability, organizational functioning, and regulatory oversight. Cheryl was the primary author of eight major CSB investigative publications; several of these reports, including the BP America Refinery Explosion and Fire Investigation Report (2007), have received global recognition for their contributions to the advancement of safety within complex and high-hazard work environments.
She led the human factors analysis for numerous investigations, including but not limited to the Macondo Deepwater Horizon offshore well blowout and the BP America refinery explosion. Her areas of focus are human and organizational factors, including human performance, safety performance indicators/metrics, and organizational culture. MacKenzie is a graduate of Cornell University with a MS in Human Environment Relations, specializing in Human Factors and Ergonomics.
