Ng, Sin Ying (Albe) Image

I am Albe, a PhD student under the supervision of Dr. Wai Sze Chan. I received my bachelor’s degree in the Department of Psychology at HKU. I am interested in the psychopathology of complex trauma and the resilience factors facilitating posttraumatic growth. My research project focuses on the role of sleep disturbance in the relationship between child abuse and emotional and behavioural adjustment. I aspire to equip and empower caregivers with skills to take care of emotionally disturbed children so that healing can take place in everyday life, beyond the therapy room.
