My long-term research goal is to better understand the evolution of cognitive abilities in human and non-human animals. My current research has focused on whether non-human animals form cross-modal representations of familiar individuals and species as well as underlying perceptual system behind this. I'm also interested in multi-species comparison and I have studied a wide variety of species, including chimpanzees, four species of old-world monkeys, three species of new-world monkeys, pigeons, dogs, horses. These investigations were conducted in the laboratory using both operant and non-operant paradigms to measure cognitive function.

After completing my degree, I was awarded a JSPS(Japan Society for the Promotion of Science) Postdoctral fellowship for research abroad and moved to the Yerkes National Primate Research Center. I studies social representation in rhesus macaques such as face perception, cross-modal representation, and dominance relationship with Prof Robert Hampton. In 2009, I moved back to Japan to carry my second postdoc at Primate Research Institute, Kyoto University. From 2010, I moved to my current position as an assistant professor in CICAPS.
