on appointment

My research focuses on understanding the factors limiting our ability to process the information relevant to perform a given cognitive task. The cognitive system underpinning this ability is known as working memory. In my research, I use behavioral tasks and computational modeling to examine: (1) how we create, maintain, and manipulate representations in working memory; (2) why we forget information and whether we can take active measures to prevent the loss of information (e.g., by rehearsing it); (3) how attention can be used to prioritize the selection and use of information;  and (4) the impact of lifelong experiences (such as bilingualism) and of healthy aging to the plasticity and functioning of the cognitive system.

Research interests

  • working memory and working memory capacity
  • declarative and procedural working memory
  • attention to working memory contents (i.e., "retro-cue benefit")
  • rehearsal and refreshing
  • multi-tasking (e.g., task-switching)
  • executive functions
  • aging
