Dr. LIU Xiaonan

Assistant Professor, Department of Psychology, CUHK

Biography

Xiaonan Liu is an Assistant Professor in the Department of Psychology at The Chinese University of Hong Kong. He received his Ph.D. from Carnegie Mellon University. Before his current position, he held a variety of academic roles at the University of California, Davis, and Xiamen University. In 2022, Dr. Liu was elected to the prestigious Memory Disorders Research Society.

The focus of Dr. Liu’s lab lies in employing behavioral studies, neuroimaging (EEG and fMRI), machine learning, and biologically based computational modeling to investigate the dynamic strengthening, alteration, and integration of memory, as well as the brain structures that support these processes. Additionally, Dr. Liu’s lab has developed a translational program that combines neuroimaging and machine learning techniques to improve memory in individuals with psychotic and neurocognitive disorders.
