Chia-Yu (Millie) Liu
I'm a Mandarin & English bilingual researcher who is also "multilingual" in research methods. I study how hearing loss relates to mental health and cognitive aging. I finished my M.S. in the Department of Audiology and Speech-Language Pathology at Asia University in January 2026, and I now work with the Department of Psychiatry at Chi Mei Medical Center. I work in three research languages.
- Clinical insight and psychology. I trained in educational psychology at National Tsing Hua University and then in speech-language pathology. This taught me to see each patient as a whole person, not just a test score. My undergraduate thesis was on gelotophobia, the fear of being laughed at. Four years later I was co-first author of a meta-analysis of laughter therapy for depression and anxiety, in Journal of Psychiatric Research.
- Neuroscience tools. As a research assistant I assisted with EEG and fMRI studies of humor and emotion, and tested participants in EEG and eye-tracking studies of aphasia.
- Large-scale data analysis. I work on dose-response meta-analyses and TriNetX cohort studies, using R and Stata. My other 2026 papers look at cochlear implants, sleep medicines and falls in dementia, vitamin D for depression, and diabetes and weight-loss drugs in psychiatric patients.

Working together
I help clinicians, researchers and graduate students with the statistics of meta-analyses and cohort studies, part-time. I do not write theses or coursework, and I work with de-identified data only. Email me with a short description of the project.
