I currently work at Araya Inc. studying neural mechanisms of curiosity. I received a Ph.D. at Neural Computation Unit at Okinawa Institute of Science and Technology (OIST) under supervision with Prof. Kenji Doya. I decided to work in Araya Inc. as a researcher for a new adventure with CEO Dr. Ryota Kanai (former Reader at Sussex University).
My current projects are:
Neural structural/functional correlates of curiosity
Dynamical brain states of an animal model of major depression
Optogenetic interrogation of brain-wide dynamics by the serotonergic system [Hamada et al., Nat Commu, 2024]
Systems Neuroscience
Cognitive Neuroscience
Neuro-phenomenology
Positive Psychology
