- My research investigates issues in aerospace biomedical engineering and human physiology in extreme environments. My focus is to develop technologies to measure and mitigate the body’s adaptations to these unique conditions. I investigate human performance, biomechanics, and injuries in extravehicular activity (EVA) with wearable sensing systems. I have also developed methodologies for assessing changes in intracranial pressure (ICP) through the ear, by measuring changes in cochlear distortion product otoacoustic emissions. I have investigated the fundamental physiology of the eye and how its shape and pressure are also altered, including under artificial gravity centrifugation. I also investigate behavioral health outcomes in isolated, confined environments, investigating the use of virtual reality for attention restoration and relaxation. This work has been extended to assess alternative reality technologies (e.g. virtual and augmented reality) for spacecraft habitat design.
