Ph.D. student

Research topics:

  • Cognitive neuroscience
  • Cognitive action control
  • Healthy aging
  • Multimodal neuroimaging of the neural networks of dual-task performance

Methodological topics:

  • Functional and structural imaging
  • Resting-state fMRI (rs-fMRI)
  • Machine Learning

The primary goal of my Ph.D. research project is to elucidate neural correlates of age-related differences in cognitive action control, more specifically, in dual-task performance. For this purpose, I will make use of a multimodal neuroimaging study (including structural MRI, task-based fMRI and rs-fMRI), a separate behavioral study, as well as detailed cognitive and motor-related ability assessments. After exploring the behavioral changes, I will analyze how regional brain function, as well as interregional brain connectivity during the task, is associated with the age-related differences in dual-task performance. To gain a more holistic perspective of cognitive action control, we will examine how other cognitive domains, such as attention, working memory and inhibition, mediate the results. An additional approach will be to investigate how well individual dual-task performance can be predicted from brain structure, connectivity, and activity by implementing machine-learning-based out-of-sample prediction analysis.
