Study and prevention of psychiatric and neuro-degenerative diseases
Xiangfei has broad research interests in population health and neuro-psychiatric epidemiology in general and aging populations, using a wide range of techniques to research the roles of genetic, psycho-socio environmental risk factors and their interactions of common mental disorders across the life span, especially focusing on the importance of prevention strategies in diverse ethno-cultural environment.
The etiology of mental disorders remains unclear. It is widely accepted that a complex interplay of genetic and psycho-socio environmental risk factors, and their interactions cause mental disorders.
Even through psychotropic medications, psychotherapy, and alternative therapies have been widely used in the clinical practice, their population impact is limited due to the rising treatment demands and limited resources for mental health care services. There is a lack of population initiatives or large-scale trials for the prevention of mental disorders.
Because of the nature of mental disorders, people with different genetic backgrounds maybe associated to varying degrees of vulnerabilities for mental disorders and thus respond differently when faced with similar psycho-socio environmental risks.
Mental disorder prevention strategies should embody a life course approach, that draws attention to the powerful connection between experiences/events early on and their consequences over time.
Evidence-based prevention strategies for common mental disorders specific to the Canadian population and Quebecers are needed, with special attention given to logical links throughout the life course.
Her research applies evidence-based epidemiological approaches to strengthen evidence and strategies for the prevention of mental disorders, will advance the understanding of the etiology and prevention of mental disorders, maximize "translational" component in which knowledge is used in a joint effort to translate discoveries into clinical and public health actions, and perhaps set an example for the prevention of other complex diseases.

Xiangfei Meng was trained in multiple disciplines. Her previous training consists of a Bachelor degree in Preventive Medicine, a Master Degree in Epidemiology & Biostatistics and a Doctor degree in Medical Genomics (Genetic Epidemiology direction). She then successfully completed her postdoctoral training, which was funded by CIHR-PHARE (Public Health and the Agricultural Rural Ecosystem) and SHRF (Saskatchewan Health Research Foundation).
