My research centers on lifespan development in self-concepts and decision-making processes, with their implications for well-being. I earned my Ph.D. in Developmental Psychology from Cornell University (2026) and my B.Sc. in Psychology and B.A. in Economics from Peking University (2020).
In the Self, Aging, Goals, and Adaptation Lab, we adopt quantitative methodologies, including behavioral experiments and large-scale surveys, supplemented with qualitative evidence to explore the following fundamental questions of everyday life:
How do we stay "ourselves" while constantly changing? This research area examines self-continuity — the thread connecting who we were, who we are, and who we will become. We study how people construct and maintain a coherent sense of self across the past, present, and future, and why some people feel more connected to their future selves than others.
Aging is not decline — it's change, and change unfolds differently at every life stage. This research area takes a lifespan perspective on psychological development, tracking how self-perception, motivation, and cognition shift from early adulthood into later life, and what these shifts reveal about the aging process itself.
Every decision is, in some sense, a negotiation between our present self and our future self. This research area investigates how people set and pursue goals, weigh short-term versus long-term outcomes, and make choices that shape their future, and how these decision processes evolve across the lifespan.
How people adapt — to age, to setbacks, to changing life circumstances — has real consequences for well-being. This research area examines the links between self-continuity, decision-making, and psychological adaptation, asking how a strong connection to one's future self supports healthier choices, greater resilience, and better long-term well-being.
