Ryo Kitada, Ph.D

Nanyang Associate Professor, School of Social Sciences, Nanyang Technological University, Singapore

I am a cognitive neuroscientist who has been fascinated by many questions on mind and brain, such as how our mind and brain work, how they develop and how they become atypical. I completed my PhD in Neuroscience at Kyoto University, where I was supervised by Dr. Michikazu Matsumura. I was then a postdoctoral fellow and research associate under supervision of Dr. Susan J. Lederman. I became an assistant professor at National Institute for Physiological Sciences (NIPS) Japan in 2008. I have started my own lab at Nanyang Technological University. I have been engaged in projects with many collaborators from different disciplines (e.g., economics, psychology, medicine and engineering).

My main focuses of research are (1) to understand the mechanisms underlying multisensory perception and social cognition and (2) how innate and postnatal experience are interacted with each other to develop them. I have been employing both psychophysics and neuroimaging techniques (such as functional magnetic resonance imaging, fMRI) to address these questions.

Webpage of the lab is now open!
