What enables humans to thrive amid constant change? From global crises like pandemics to personal transitions such as becoming a parent,
life presents us with ever-shifting demands. Successfully navigating this dynamic landscape represents one of the fundamental challenges any psychological
system must solve: how to maintain coherent functioning while continuously adapting to novel circumstances.
My research highlights the remarkable flexibility of the human mind. In response to new demands, our minds dynamically reallocate priorities, reassess
threats and opportunities, and revise strategies to achieve emerging goals. I aim to advance a science of psychological flexibility as a functional
recalibration system, investigating how it coordinates shifts in motivation, cognition, emotion, and behavior, drawing on data across intrapersonal,
interpersonal, and cross-cultural levels of analysis.
My work explores three core areas: (1) the mechanisms that shape shifts in priorities and how they recalibrate the way we perceive and navigate
the social world; (2) the functions of this flexibility in managing goals and affordances; and (3) its implications for psychological well-being
and behavior change. Understanding these dynamics reveals a core feature of human psychology and offers insight into how people can more effectively
navigate today’s increasingly diverse, complex, and rapidly changing world.
