Wai Ting Siok, Ph.D.

Principal Investigator, Shenzhen Institute of Ne

Dr. Siok received her Ph.D. in Psychology and Education from the University of Hong Kong's Department of Speech and Hearing Sciences in 2001. After a two-year postdoctoral training at Stanford University Psychology Department and the Stanford Institute of Reading and Learning, Dr. Siok began her work in the Department of Linguistics at the University of Hong Kong in 2004. Dr. Siok's research focuses on bilingualism, language development and language neuroscience. Her ongoing research is aimed at determining the neural mechanisms that underlie reading in normal and dyslexic children. She has published a lot of papers in prestigious journals, including Nature, PNAS and Current Biology.
