I am a cognitive psychologist specializing in the study of cognitive control, stimulus-driven
behaviors, and their modulation across the lifespan. My research focuses on understanding
how automatic processes, such as reading or word–color associations, interact with task
demands and how individuals regulate these processes under varying contexts of conflict
and distraction.In my doctoral and postdoctoral work, I have designed and conducted large-
scale Stroop experiments to investigate information conflict, task conflict, and
stimulus–response associations. My studies have shown that while older adults often
experience declines in some aspects of inhibitory control, their ability to maintain task sets
and engage in stimulus-driven tasks remains relatively intact. These findings advance
theoretical models of aging and cognitive control by disentangling preserved and impaired
mechanisms.
