My main research interests lie in forensic speech science, sociophonetics, acoustic phonetics and Bayesian analysis. I did my PhD in forensic speech science where I investigated the issue of sampling variability in forensic voice comparison. My PhD research contributes to the on-going discussion of validity and reliability in forensic evidence comparison showing that forensic experts should focus on measuring and minimising uncertainty, not maximising discriminability. Meanwhile, I have also employed a Bayesian model to reduce the degree of uncertainty and improve reliability.
I am currently a postdoctoral researcher at the Department of Chinese and Bilingual Studies, The Hong Kong Polytechnic University. I work on the SCOLAR funded project Developing a Social Robot for Cantonese and Mandarin Speech Prosody Training in Children with Autism Spectrum Disorder with Si CHEN (PI).
