Xupeng Mao holds both a BA and an MA in Sociology from East China Normal University. Xupeng’s research interests include older adults’ well-being, family relations, social support in later life, social welfare policies and programs. Xupeng’s proposed dissertation uses two large national representative datasets to examine the relationship between social support and Chinese older adults’ subjective well-being, and to identify the groups most vulnerable to low subjective well-being and the types and sources of social support that may promote the older adults’ subjective well-being. This dissertation will contribute to filling in the knowledge gaps in the relationship between social support and Chinese older adults’ subjective well-being. The findings from this dissertation as a whole will help social work professionals to provide the most suitable services, programs, and policies to enhance the subjective well-being of the older adults and their families in China.
