Martinos Center for Biomedical Imaging in the Massachusetts General Hospital in same year. He also attended intensive courses of transcranial magnetic and electrical stimulation in Harvard Medical School, Universitätsmedizin Göttingen and University Medical Center Utrecht from 2014 to 2016. His current research interests reside in pharmacological and non-pharmacological interventions for geriatric depression, structural and functional brain mapping, non-invasive transcranial brain stimulation for mood disorder and cognitive impairment in elderly. He obtained Distinguished Young Fellow Award given by the Hong Kong Academy of Medicine in 2018.

Research Interests
