Dr Ariel Zeleznikow-Johnston is a neuroscientist at Monash University, where he investigates novel methods for characterising the nature of conscious experiences to aid in the ongoing quest to understand the neural basis of consciousness. In 2019, he obtained his PhD from The University of Melbourne, where he researched the mechanisms by which genetic and environmental factors affect cognition in healthy and diseased brains. He has published widely across the field of cognitive neuroscience, from the decline, preservation, and rescue of cognitive function at different stages of the lifespan, through to characterising people’s conscious experience of colour. His first general-audience book, which makes the neuroscientific, philosophical, and sociological case for providing universal access to a brain preservation procedure capable of placing dying people in stasis, is due to be published in late 2024.
