Personal profile
Personal profile
Dr Lorinda Kwan-Chen is a clinician-scientist and senior speech-language pathology educator with more than three decades of experience in adult neurogenic communication and swallowing disorders. Her research focuses on Primary Progressive Aphasia (PPA) in Chinese and Cantonese-speaking populations, Parkinson’s disease-related dysarthria, post-stroke aphasia, apraxia of speech, and neurodegenerative dysphagia.
She leads the Cantonese arm of an international multi-centre PPA research programme, collaborating with UCSF, UCL, and international PPA networks. Her recent work has appeared in Neurology, and Alzheimer’s & Dementia, advancing cross-linguistic understanding of PPA diagnosis, communication profiles, and intervention.
Dr Kwan-Chen pioneered community-based rehabilitation and early teletherapy models for stroke, dementia, Parkinson’s disease, and related neurological conditions in Hong Kong. She has trained more than 1,000 bilingual speech therapists and postgraduate students, and received Faculty Top 10% Teaching Awards in 2019/20, 2023/24, and 2025/26. She serves as Council Member of the Hong Kong Parkinson’s Disease Foundation, authoring 70+ public education articles and delivering 20+ seminars, and as founding member and committee member of the Hong Kong Institute of Speech Therapists.
Research interests
Dr Lorinda Kwan-Chen’s research focuses on Chinese and bilingual adult neurogenic communication and swallowing disorders, integrating clinical linguistics, neuroscience, evidence-based intervention, telepractice, and community-based rehabilitation.
Her primary research programme examines Primary Progressive Aphasia (PPA) and language-led neurodegeneration in Chinese-speaking populations. She leads the Cantonese arm of the Chinese Language Assessment in Primary Progressive Aphasia collaboration with the University of California San Francisco, and contributes to international PPA networks, including cross-linguistic profiling, COS-PPA outcome-set development, caregiver support, and intervention research. Her interests include lexical tone processing, dysgraphia, noun classifier processing, lexical retrieval therapy, script intervention, aphasia-friendly communication, conversation effectiveness, and caregiver burden.
Recent publications in Neurology, Alzheimer’s & Dementia, Neurocase, and Parkinson’s Disease anchor this programme of work, spanning lexical tones, dysgraphia, noun classifiers, cross-linguistic PPA profiles, COS-PPA recommendations, Cantonese nonfluent/agrammatic PPA, and Parkinson’s disease-related speech impairment.
A second major strand focuses on Parkinson’s disease-related dysarthria, prosody, and neurodegenerative dysphagia. This includes emotional and linguistic prosody, lexical tone production and perception, utterance-final particles in Cantonese speech, and the impact of medication and deep brain stimulation on communication and swallowing.
Her work also addresses post-stroke aphasia, apraxia of speech, dysarthria, discourse, functional communication, and family communication support. Across these areas, she is interested in telepractice, hybrid rehabilitation, patient-perceived benefit, caregiver involvement, and sustainable community-based models of care.
Her scholarship further extends to clinical education, evidence-based practice, bilingual professional training, reflective supervision, e-learning, telepractice competence, and international capacity-building in speech-language pathology.
