My research centers on two interconnected aspects of the aging process: self-continuity and decision-making, and their implications for lifelong well-being. These topics address fundamental questions of everyday life:
(1) How do we view ourselves across the past, present, and future?
(2) How do we make decisions that shape our future?
To do so, I combine quantitative methodologies with qualitative evidence, including behavioral experiments, large-scale online surveys, and text responses, and apply advanced statistical models to uncover nuanced patterns in the data.


Self-continuity, the perceived connectedness with our past and future selves at different time points, is a cornerstone of self-identity. It is associated with preventive decisions, health-promoting behaviors, life satisfaction, and well-being at both individual and societal levels, while lower self-continuity is linked to depression and suicidal ideation (Sedikides et al., 2023). Yet, our understanding of how self-continuity varies across contexts remains limited. To address this gap and inform both implications for subjective well-being and health policies, my research investigates the temporal pattern of self-continuity across age, culture, and major life transitions.
How we perceive ourselves plays a vital role in shaping our decisions. For older adults, age-related changes in cognitive resources present unique challenges to decision-making. In response, I examine how older adults’ view of future selves and their age group influence decision-making in intertemporal and risky contexts.


According to the Socioemotional Selectivity Theory (Carstensen, 1992), as people age, they prioritize their social and emotional goals. This shift has important implications for older adults’ judgment and decision-making, particularly given their heightened vulnerability to elder abuse and financial fraud. My ongoing work aims to uncover the age-related differences in judgments and decisions in social contexts.
Applying advanced methods to research. My doctoral research employed advanced quantitative methods to investigate age-related differences in self-continuity and decision-making. These approaches address methodological gaps in prior literature, allow for the detection of nuanced effects, and enable deeper investigation into the mechanisms underlying observed age differences.
Open science practices. I am committed to conducting transparent and reproducible research and share my pre-registrations, analysis scripts, study materials, and/or data through publication supplements and platforms including AsPredicted.org and OSF.io.
