His work centers on understanding the neural mechanisms by which emotions influence visual perception and decision-making, particularly through neuromodulatory systems such as those involving arousal and affective valence. He employs neuroimaging and circuit-level analysis to explore cortical and subcortical pathways that link emotional states to sensory input and behavioral output.

Dr. Leong teaches key courses in his domain, including Affective Science, Biopsychology, Neuroscience, and Neuroimaging, contributing to both undergraduate and graduate training in psychological and brain sciences.

His research program emphasizes tool development for measuring brain circuit structure and function, aiming to uncover fundamental principles of emotion-perception-action integration. Although specific publications and advising records are not listed, his lab actively welcomes students from diverse backgrounds to engage in scientific inquiry.

Education:

• Ph.D., Stanford University, 2019
• B.A., University of California, Berkeley, 2010

Dr. Leong’s interdisciplinary approach positions him at the forefront of affective neuroscience, combining psychological theory with systems-level neuroscience methods to advance understanding of the emotional brain.
