Multilingual speech AI
Developing and evaluating deep-learning models for depression screening from English and Chinese clinical speech, with an emphasis on cross-language generalisability and clinically meaningful evaluation.
Health AI researcher · London, UK
I am a PhD candidate in Health Informatics at King's College London. My research brings together machine learning, digital biomarkers, epidemiology and medical statistics to support more accessible and interpretable healthcare.
Bio
My doctoral work combines evidence synthesis, diagnostic-accuracy assessment and multilingual deep learning for automatic speech-based depression screening. I also designed and built a working iOS prototype that translates this research into a mobile health application.
Alongside my PhD, I lead an analytical work package within the eLIXIR-BiSL programme, working with more than 30,000 repeated observations from over 18,000 infants across linked NHS datasets. Before research, I worked in data analytics and governance at Deloitte Consulting and Bank of Jilin.
I use Python, PyTorch, R, SQL and Swift, and enjoy collaborating across clinical, academic and data teams to turn complex methods into clear, responsible and reproducible outputs.
Research
Developing and evaluating deep-learning models for depression screening from English and Chinese clinical speech, with an emphasis on cross-language generalisability and clinically meaningful evaluation.
Translating research models into usable tools, including a Swift/iOS prototype that connects speech capture with automated depression-screening outputs.
Analysing linked NHS maternity, neonatal and Health Visitor records using reproducible pipelines, mixed-effects models and clinically interpretable trajectories.
