About
Dr. Laurence M. McKenna is a leading expert in sleep medicine and circadian physiology, with a particular focus on the challenges of extreme shift work and space exploration. His research investigates how non-24-hour schedules disrupt human sleep-wake cycles and performance, a field with profound implications for both deep-space missions and terrestrial safety. Dr. McKenna’s most notable contribution is his landmark study on the Phoenix Mars Lander mission, where he analyzed fatigue countermeasures for personnel forced to live on a 24.65-hour "Mars day" for 78 consecutive days. This work, cited over 60 times, demonstrated the critical risks of circadian misalignment to workplace safety and operational performance in high-stakes environments. By bridging the gap between space operations and clinical sleep science, Dr. McKenna has provided foundational evidence for developing countermeasures that protect cognitive function during prolonged alien schedules. His research continues to inform NASA’s mission planning and has broader applications for industries requiring round-the-clock vigilance, making him a pivotal figure in understanding how humans can adapt—and thrive—when Earth’s natural rhythms are left behind.
