Joshua Ong, MD has been focused on protecting astronaut health and upholding mission performance for upcoming planetary spaceflight including the Mars Mission. He is also focused on research to help prevent blindness of Earth. His work in extended reality ranges from developing NASA-funded work on augmented reality to counteract damaged astronaut vision on the anticipated mission to Mars. His work in extended reality also encompasses quantification of pupil dynamics to further understand the pathophysiology of spaceflight associated neuro-ocular syndrome (SANS), one of the largest physiological barriers to spaceflight. He serves as a peer reviewer for multiple journals and is passionate about advancing the future of spaceflight and medicine with research. He has been awarded multiple awards for his work in research. One of his lifelong passions to help translate cutting edge space medicine technologies, such as head-mounted vision technologies for astronauts, to also benefit human health on Earth and to help attenuate irreversible but preventable blindness.
