Bio: My research focuses on leveraging longitudinal datasets to explore topics in life course and aging, guided by key principles of life course theory, such as “linked lives,” “timing,” and “life-span development.” In the realm of “linked lives” and “timing,” I have conducted studies examining the relationship between social participation and older adults’ health. Notably, my recent publication in The Gerontologist demonstrates that social participation in midlife predicts better cognitive trajectories in later life, even after accounting for childhood factors, though it does not significantly predict slower cognitive decline among older Chinese adults. Additionally, an ongoing project employs propensity score analysis to assess the extent to which the relationship between volunteering and subjective well-being is influenced by contextual factors, socio-economic resources, health conditions, and social roles. My findings highlight that this association remains robust, even with an approximate 20% decline; 2) the benefits of volunteering are particularly pronounced for individuals with low socioeconomic status, aligning with resource multiplication theory. Furthermore, I explore intergenerational relationships and their impact on parental depression in multi-child aging families, guiding by the “linked lives” principle.

Beyond the Chinese context, I am investigating the effects of chronic pain on cognitive health among middle-aged and older adults in the U.S. My research identifies pain interference—such as its impact on mood, enjoyment, activity, sleep, and relationships—as a mediator in the association between pain locations and cognitive health among individuals with chronic pain.
   
Lastly, I am interested in exploring different methodologies. For example, I am interested in innovative approaches to research. My dissertation utilizes integrative data analysis and data harmonization to study cognitive trajectories across multiple datasets. Additionally, I am exploring the application of AI to enhance the validity and reliability of scoping review methodologies.
