Pik Ki's research focuses on empirical and neuroaesthetics - an area in which the psychological and neurological mechanisms underpinning aesthetic appreciation towards artwork, architecture, as well as everyday objects are studied using techniques in psychophysics, experimental psychology and cognitive neuroscience. She is also interested in visual perception and human cognition in general.

Pik Ki is currently investigating the psychological basis underlying the aesthetic appreciation of art portraits, architectural spaces, and digital art; as well as the socio-cognitive aspect of face perception. These research projects involve multi-disciplinary, cross-campus, and cross-institutional collaboration. She would be keen on supervising student research projects related to these topics at the undergraduate or postgraduate level.
