Our research program investigates how experience shapes the brain and cognition, with emphasis on bilingualism, cognitive control, neural efficiency, and aging. We integrate behavioral paradigms, EEG and neuroimaging, and quantitative methods to understand mechanisms of experience-related neuroplasticity.

Investigating how managing multiple languages influences attention, conflict monitoring, and executive function, and how these effects depend on patterns of language use and exposure.
Studying how long-term experiences, including bilingualism and cognitively demanding life contexts, contribute to cognitive reserve and the timing of age-related decline and dementia symptoms.
Examining changes in brain signal complexity, efficiency, and dynamics as markers of experience-related reorganization and adaptation.
The Institute emphasizes robust measurement, reliability, and transparent analytic workflows to support cumulative science.
