Research experiences:

My research is centered on the dose-response relationship between physical activity and mental health, as well as between physical activity and suicidal ideation and behavior. The aim is to tailor the modality and dosage of physical activity to the specific characteristics of different groups, such as age, gender, and body mass index, in order to precisely promote mental health and effectively reduce the incidence of suicidal thoughts and actions. Additionally, the research delves into the neurobiological, psychosocial and behavioral mechanisms underlying the connection between physical activity and mental health, suicidal ideation, and behavior, with the goal of providing a solid scientific foundation for further clinical applications. I published an article as the first author in the "JAMA Pediatrics". The article used a multi-level meta-analysis method to explore the relationship between physical activity interventions and the mental health of children and adolescents with neurodevelopmental disorders, including cognitive function, psychological well-being, internalizing and externalizing problems, and identified potential moderators related to methodology, participant characteristics, types and doses of physical activity, as well as the interactions among these moderators. Subsequently, I published another article as the first author in the "American Journal of Preventive Medicine," further exploring the potential neurobiological, psychosocial, and behavioral mechanisms underlying the relationship between physical activity interventions and the mental health of children and adolescents with neurodevelopmental
