Brief summary of research over the last five years:

  • My work has a strong focus on neuromodulation, which seems to be responsible for the dynamics and adaptivity of human cognition. Combining a cognitive neuroscience perspective with a focus on individual differences, I study, by means of a wide range of computerized tasks, whether and how (social) cognition processes and their neurobiological mechanisms are affected by these factors across the life span in healthy and psychiatric population.

  • In the last two years I focused my interest on the effect of nutritional interventions (tyrosine, tryptophan, probiotics) on cognition. My work support the idea that the food one eats has a bearing on one's state of mind. The food we intake may thus act as a cognitive enhancer that modulates the way we think and perceive the physical and social world.
