My primary research interest is to understand how perception and cognition relate to the activity of neurons in the brain. In my lab we are exploring the role of different prefrontal areas in visual perception and visual working memory.
We use chronically-implanted multielectrode arrays to record activity from multiple single neurons during the performance of behavioural tasks. This information is then used to try to understand how populations of neurons encode and decode the task-related information.
In addition to recording brain activity, these implanted electrodes can be used to inject current, or microstimulate, small areas of the brain. We use this technique to assess the effect of prefrontal microstimulation on cognitive performance.
Finally, in collaboration with engineers in A*STAR and NUS, my group is involved in the development of neurotechnologies, such as cortical brain-machine interface and peripheral nerve prosthesis.
I am an Assistant Professor at the Department of Psychology of the National University of Singapore. My lab is located in the Singapore Institute for Neurotechnology (SINAPSE; directions here). I have a joint appointment at Institute of Molecular and Cell Biology (IMCB) in A*STAR.
