As a speech scientist, my research goal is to bridge the large gap between human intelligence and artificial intelligence. I have recently completed my Ph.D. in Speech, Hearing and Phonetic Sciences from University College London. My Ph.D. project focuses on a computational model of speech acquisition. My research is primarily concerned with the basic mechanisms underlying speech production and perception using computational simulations, behavioural experimentations and neurophysiological techniques such as SEEG. I am also interested in speech emotion, speech prosody and its interaction with syntax. So far, I have published 8 SCI/SSCI journal articles, 11 EI indexed papers and 8 conference papers or abstracts. 教育经历 (Education) 2017.09-2022.12 Ph.D. in Speech Hearing and Phonetic Sciences, University College London, UK 2015.09-2016.09 MA in Linguistics (Distinction), The University of Hong Kong, Hong Kong 2010.09-2014.07 BA in Japanese Language and Literature, Ocean University of China 工作经历 (Work Experience) 2023.02-Present Assistant Professor, Harbin Institute of Technology, Shenzhen 2016.10-2017.08 Research assistant, The Hong Kong Polytechnic University 2014.07-2015.08 Staff, Waseda University (Japan) Shanghai office
