I have been working as a clinician (pediatrician and anesthetist) since 2001. The amazing discovery of hibernating tropical primates, which was done by Kathrin Dausmann on 2004 (Dausmann KH, Nature, 2004), inspired me to take a step in the field of biomedical applications of natural phenomena like hibernation. I studied the mechanism of homeostatic regulation of mammalian sleep using quantitative sleep evaluation for genetically modified animals at Laboratory for Synthetic Biology, RIKEN, Kobe. From 2015, I moved to Laboratory for Retinal Regeneration, RIKEN and I am focusing on understanding of active hypometabolsim in mammals. The final goal is to develop a safe method to make human hibernate for clinical applications.
