We obtain information about the external world through multiple sensory modalities, including vision, audition, and touch. To accurately perceive external events, the brain must estimate when sensory signals occurred and whether they originated from the same event. This requires the flexible adjustment of perceived timing in response to changes in the environment. My research aims to clarify the learning mechanisms underlying such flexible timing perception.

Features from different sensory modalities can be naturally associated with one another, as in the correspondence between high-pitched sounds and higher spatial locations. I investigate how such cross-modal correspondences influence multisensory integration and attention. Through this work, I aim to clarify what kinds of information are, or are not, used in perceptual and cognitive processing in multisensory environments.

Synesthesia is a phenomenon in which a sensory input elicits an additional sensory experience that would not ordinarily accompany it, such as seeing a specific color when viewing a letter even though that color is not physically present. Although synesthesia is a distinctive conscious experience found only in some individuals, its development is also known to be strongly influenced by postnatal learning experiences. By investigating the relationships between synesthesia, letter learning, and perceptual processing, I explore whether this seemingly unusual phenomenon can be explained in terms of general mechanisms of perception and learning.

Recently, I have also been using EEG to investigate the mechanisms underlying temporal fluctuations in perception and cognition based on neural oscillations.
