My research focuses on the neural mechanisms of subjective perception. Specifically, I explore the neural basis of time and numerosity perception by combining psychophysical experiments with neuroscientific techniques such as neuroimaging and brain stimulation.

In the future, my work will also address how human brain maximizes its efficiency in terms of neural representations and information processing.
